I want to find experimental realizations of routing or shuttling trapped ions in three dimensions in a quantum computer. I want to find papers which specifically focus on routing and shuttling, and I only want papers that talk about 3 dimensional shuttling, not 2 or 1 dimensions.

Report

The search identified a single paper that clearly presents an experimental realization of 3D shuttling of trapped-ion qubits in a quantum computing environment [1], with additional papers discussing related theoretical proposals and architectures for multi-layered ion traps relevant to 3D quantum information processing [2, 4, 7].

Details:

Main Experimental Result:
- [1] High-fidelity transport of trapped-ion qubits in a multilayer array (2023):
  - This paper demonstrates the experimental shuttling of single Mg$^+$ ions within a scalable 3D trap-array architecture containing up to thirteen sites.
  - Achieves a success rate of over 0.99999 for shuttling ions from a dedicated loading hub to multiple sites.
  - Demonstrates the preservation of coherence in ion qubit superposition states during inter-site shuttling, making it relevant for large-scale quantum computing applications.
Related Proposals and Simulations:
- [2] Bilayer crystals of trapped ions for quantum information processing (2023):
  - Describes using Penning traps to form bilayer crystals where ions self-organize into two well-defined layers.
  - Notes the potential for extending to multilayer crystals, thus contributing to increased dimensionality in trapped ion systems.
- [4] Surface Ion Trap Designs for Vertical Ion Shuttling (2019):
  - Proposes a novel planar surface electrode ion trap designed for vertical (Z-axis) shuttling with detailed simulations.
  - Presents the design as a conceptual framework for vertical ion movement relevant to 3D shuttling.
- [7] Three-dimensional lattice of ion traps (2009):
  - Proposes a 3D ion trap configuration forming a simple cubic arrangement.
  - Describes the feasibility of individually addressing ions in this lattice but lacks experimental validation of 3D shuttling.
Broad Relevance but Not Directly Focused:
- Several papers ([3, 5, 6, 8, 9, 10, 11, 12]) describe advancements in ion-trap quantum computing or shuttling in lower dimensions but do not specifically address 3D ion shuttling experimentally.

Conclusion:

The search yielded one key experimental study [1] confirming the successful 3D shuttling of trapped ions with preserved qubit coherence, critical for scalable quantum computing. Additional theoretical proposals and architectures [2, 4, 7] provide supplementary insights into the potential for 3D shuttling, suggesting ongoing development in this field. These findings are instrumental for researchers aiming to enhance interconnectivity and scalability in quantum systems through 3D ion routing.

[35] Microfabricated Paul traps for levitating and shuttling of ions and charged particles H. Rattanasonti Journal Not Provided 2015 - 0 citations - Show abstract - Cite Abstract: Trapped ions in Paul traps (radio frequency ion traps) are a promising candidate for the realization of a quantum computer. To date, experimental demonstrations of quantum computing and information processing with trapped ions have been limited to small numbers of quantum bits (qubits). The most prominent challenge to realise ion-trap quantum computation is to scale the system and control a large number of trapped ions coherently. Surface-electrode ion trap designs which are amenable to various microfabrication techniques offer a path to achieve this. In this work, design, fabrication and key operations of two types of surface-electrode ion traps, i.e. a Y-junction trap and a two-dimensional (2D) hexagonal lattice trap developed towards scaling ion-trap architectures, are presented. The steps involved in the fabrication of the ion-trap devices included photolithography, wet etch (hydrofluoric acid etch) and dry etch (deep reactive ion and inductively coupled plasma etching), and metal evaporation. The devices were fabricated on SOI substrates with different buried oxide thicknesses (i.e. 5 µm and 10 µm) and different metals for the trap electrodes (i.e. gold and aluminium). An extremely high-breakdown voltage up to 1 kV was measured in vacuum for the SOI-built test devices with a 10 µm-thick buried oxide formed by oxide film-to-oxide film bonding process. This is attributed to the deep V-shaped undercut profile of the buried oxide layer which resulted in a large breakdown path length, and so mitigating surface breakdown effects. Owing to the V-shaped undercut profile, the surface breakdown voltage was improved by 15% for the devices fabricated on SOI substrates with a 10 µm-thick buried oxide. In the first experiment, the demonstration of ytterbium ( 174 Yb + ) ion trapping in the 2D hexagonal lattice trap is achieved with a relatively long lifetime of a laser-cooled ion up to 90 minutes and ≤ 5 minutes without cooling in ultra-high vacuum system. The 2D lattice trap design allows for reliable trapping of 2D ion lattices, rudimentary shuttling between lattice sites and deterministic introducing of defects into the ion lattice. Based on all these abilities, such a 2D lattice trap with the predicted reduction of lattice spacing down to 32 µm can be configured as a versatile architecture for 2D quantum simulations with trapped ions. In the second experiment, microparticle trapping in the 2D lattice trap, performed in air, is achieved with the longest trapping lifetime of 60 minutes. Both gold and aluminium-coated electrodes also lead to comparable trapping performances. Furthermore, the in situ levitation of microparticles is successfully demonstrated at the maximum levitation height of 30 µm. This ability provides additional control on the trapping height which increases the overall functionality of the 2D lattice trap. 4.7% topic match

[39] Automated Positioning Control for Trapped-Ion Quantum Registers Janine Nicodemus Journal Not Provided 2017 - 1 citations - Show abstract - Cite Abstract: Trapped ions in a segmented Paul trap are a very promising candidate to implement a scalable quantum logic processor. To address individual ions and to perform two-qubit entanglement gates between specific ions we perform shuttling operations, such as movement of ions between memory and laser interaction zones, ion crystal separation and rearrangement of ions in linear strings. To perform multiple high fidelity quantum gates, these shuttling operations have to be carried out on short time scales (e.g. < 30μs) and with minimal induced motional excitation. In this thesis, two advances towards fast ion shuttling and high fidelity quantum gates are presented. First, the “Segmented Ion Trap CONtrol System” (SITCONS) software framework, which allows for an automated generation of optimized voltage waveforms for multi-qubit register shuttling, is introduced. During this work, the first version of the framework was completed and integrated in the experimental control software. The tool was successfully used to generate and test voltage ramps, to accomplish ion crystal separation and ion crystal transport along the trap axis. Automatically generated transport over multiple segments with low motional excitations was successfully demonstrated. The second goal of this work was to reduce the magnetic field fluctuations in the ion trap, in order to reduce the decoherence of our magnetic field sensitive 40Ca+ spin qubit, which in turn allows for higher quantum gate fidelities. To characterize the existing permanent magnet setup, a temperature sensor with a resolution of 0.01 ◦C was installed. In combination with these temperature measurements, a characterization of the long-term drifts of the qubit frequency was carried out. Comparisons of these measurements showed an almost perfect correlation between the reversible temperature drift of the permanent magnets and the frequency drift. Therefore, a second-generation permanent magnet setup was developed with the aim to significantly improve the stability of the quantizing magnetic field by reducing the effects of temperature drifts on the permanent magnets. Two counteracting permanent magnets, namely magnets made of Sm2Co17 and NdFeB, were utilized, to passively compensate the temperature induced drift of the magnetic field magnitude at the trapped ion location. As a result, the dependence of the magnetic field drift on the temperature could be reduced by about 60 %. Additionally, the overall temperature drift was substantially reduced via technical measures. In total, a tenfold reduction of the total qubit frequency drift in a long-term measurement (> 8 h) was achieved, which will be of significant importance for upcoming experiments with multiple high fidelity quantum operations. Randomized benchmarking was performed with the previous and improved permanent magnet setup to allow for a direct comparison and showed that mean single qubit gate fidelities after idle times could be significantly increased. For instance, the mean single qubit gate fidelity for 10 logic gate operations, with an idle time of 0.4 ms after each gate, could be increased from 97.3 % to 99.1 %. 4.3% topic match

[40] Towards microwave based ion trap quantum technology S. Weidt Journal Not Provided 2014 - 1 citations - Show abstract - Cite Abstract: Scalability is a challenging yet key aspect required for large scale quantum computing and simulation using ions trapped in radio-frequency (rf) Paul traps. In this thesis 171Yb+ ions are used to demonstrate a magnetic field insensitive qubit which has a measured coherence time of 1.5 s, making it an ideal candidate to use for storing quantum information. A magnetic field sensitive qubit is also characterised which can be used for the implementation of multi-qubit gates using a potentially very scalable scheme based on microwaves in conjunction with a static magnetic field gradient instead of using lasers. However, the measured coherence time is limited by magnetic field fluctuations and will prohibit high fidelity gate operations from being performed. To address this issue, the preparation of a dressed-state qubit using a microwave based stimulated rapid adiabatic passage (STIRAP) pulse sequence will be presented. This qubit is protected against the noisy environment making it less sensitive to magnetic field fluctuations. The lifetime of this qubit is measured to demonstrate its suitability for storing quantum information. A powerful method for manipulating the dressed-state qubit will be presented and is used to measure a coherence time of the qubit of 500 ms which is two orders of magnitude longer compared to the magnetic field sensitive qubit. It will also be shown that our method allows for the implementation of arbitrary rotations of the dressed-state qubit on the Bloch sphere using only a single rf field. This substantially simplifies the experimental setup for single and multi-qubit gates. Furthermore, this thesis will present a experimental setup capable of successfully operating microfabricated surface ion traps. This setup is then used to operate and characterise the first two-dimensional (2D) lattice of ion traps on a microchip. A unique feature of the microfabrication technique used for this device is the extremely large voltage that can be applied which allows long ion lifetimes along with large secular frequencies to be measured, demonstrating the robustness of this device. Rudimentary shuttling between neighbouring lattice sites will be shown which could be used as part of a efficient scheme to load a large lattice of ions. One of the many applications of a 2D lattice of ions lies in the field of quantum simulations where many-body systems such as quantum magnetism, high temperature superconductivity, the fractional quantum hall effect and synthetic gauge fields can be simulated. It will be shown how making only minor modifications to the microchip the ion-ion separation can be reduced sufficiently to offer an exciting platform for the successful implementation of 2D quantum simulations. A theoretical investigation on the optimal 2D ion trap lattice geometry will also be presented with the aim to maximise the ratio of ion-ion coupling strength to decoherence from motional heating of the ions and to laser induced off-resonant coupling. 4.3% topic match

[58] Controlled inter-site coupling in a two-dimensional ion trap array F. Hakelberg Journal Not Provided 2019 - 0 citations - Show abstract - Cite Abstract: The understanding of quantum mechanical systems is essential to modern physics and its applications. However, already for entangled systems of a few tens of constituents, exact numerical simulations on classical computers can become impossible. Quantum simulators based on well-controlled quantum system might provide the only effective approach to these systems. Trapped atomic ions offer a uniquely precise and controllable platform. They are used as platforms for, e.g., future quantum computers, quantum simulators, and extremely precise clocks. Quantum-simulation problems of interest and out-of-reach for modern theoretical methods include the dynamics of one-dimensional systems on long time scales and more-than-one dimensional systems with long-range interaction. For the latter, two-dimensional arrays of ions, individually trapped and controlled above microfabricated surface-electrode traps, present a promising approach. In the first realizations so far, the inter-site distance between the ions was too large to allow for sufficient inter-site coupling. We aim for a scalable approach to an analog quantum simulator based on a two-dimensional array of individually trapped ions. As a first demonstration, we operate an array of three magnesium ions in triangular arrangement with a side-length of 40 μm. Therein, we previously demonstrated the individual control of internal (electronic) and external (motional) degrees of freedom of the ions. Here, we present the first realization of inter-site coupling in the two-dimensional array. We demonstrate the coupling by a transfer of large coherent states of motion between the sites. We investigate the influence of the amplitude of these motional states in the anharmonic trapping potential and extrapolate to future experiments on the single-phonon level. We apply the real-time control of the coupling and concatenate the two-site coupling to transfer motional excitation between all three sites of the array. To demonstrate the scalability of our techniques, we couple all three sites simultaneously and investigate the evolution of an initial excitation at one and two sites of the array. The latter shows interference effects of the different pathways in the triangle. Current motional heating rates on the order of the inter-site coupling, preclude working with single phonons near the motional ground-state. We present a new experimental apparatus and vacuum chamber which will allow in-situ cleaning of surface-electrode traps. This has shown to reduce motional heating rates by two orders of magnitude. In this apparatus, we additionally realize a magnetic-field insensitive qubit in 25Mg+ with a coherence time exceeding six seconds. We generate the magnetic field around 10.9 mT by a hybrid magnet assembly based on solid-state magnets and fine-tuned by electric coils. Once we have reduced the heating rate in the triangle trap array using the new setup, first quantum simulation experiments, investigating spin-frustration or artificial gauge fields, will come in reach. Here our triangle represents a basic, scalable, building block of future latices designed at will. 1.8% topic match

[92] Surface-electrode ion traps for scalable quantum computing D. Allcock Journal Not Provided 2011 - 10 citations - Show abstract - Cite Abstract: The major challenges in trapped-ion quantum computation are to scale up few-ion experiments to many qubits and to improve control techniques so that quantum logic gates can be carried out with higher fidelities. This thesis reports experimental progress in both of these areas. In the early part of the thesis we describe the fabrication of a surface-electrode ion trap, the development of the apparatus and techniques required to operate it and the successful trapping of 40 Ca + ions. Notably we developed methods to control the orientation of the principal axes and to minimise ion micromotion. We propose a repumping scheme that simplifies heating rate measurements for ions with low-lying D levels, and use it to characterise the electric field noise in the trap. Surface-electrode traps are important because they offer a route to dense integration of electronic and optical control elements using existing microfabrication technology. We explore this scaling route by testing a series of three traps that were microfabricated at Sandia National Laboratories. Investigations of micromotion and charging of the surface by laser beams were carried out and improvements to future traps are suggested. Using one of these traps we also investigated anomalous electrical noise from the electrode surfaces and discovered that it can be reduced by cleaning with a pulsed laser. A factor of two decrease was observed; this represents the first in situ removal of this noise source, an important step towards higher gate fidelities. In the second half of the thesis we describe the design and construction of an experiment for the purpose of replacing laser-driven multi-qubit quantum logic gates with microwave-driven ones. We investigate magnetic-field-independent hyperfine qubits in 40 Ca + as suitable qubits for this scheme. We make a design study of how best to integrate an ion trap with the microwave conductors required to implement the gate and propose a novel integrated resonant structure. The trap was fabricated and ions were successfully loaded. Single-qubit experiments show that the microwave fields above the trap are in excellent agreement with software simulations. There are good prospects for demonstrating a multi-qubit gate in the near future. We conclude by discussing the possibilities for larger-scale quantum computation by combining microfabricated traps and microwave control. 0.1% topic match

[105] Microfabrication techniques for trapped ion quantum information processing J. Britton arXiv: Quantum Physics 2010 - 14 citations - Show abstract - Cite - PDF Abstract: Quantum-mechanical principles can be used to process information. In one approach, linear arrays of trapped, laser cooled ion qubits (two-level quantum systems) are confined in segmented multi-zone electrode structures. Strong Coulomb coupling between ions is the basis for quantum gates mediated by phonon exchange. Applications of Quantum Information Processing (QIP) include solution of problems believed to be intractable on classical computers. The ion trap approach to QIP requires trapping and control of numerous ions in electrode structures with many trapping zones. In support of trapped ion QIP, I investigated microfabrication of structures to trap, transport and couple large numbers of ions. Using 24Mg + I demonstrated loading and transport between zones in microtraps made of boron doped silicon. This thesis describes the fundamentals of ion trapping, the characteristics of silicon-based traps amenable to QIP work and apparatus to trap ions and characterize traps. Microfabrication instructions appropriate for nonexperts are included. A key characteristic of ion traps is the rate at which ion motional modes heat. In my traps upper bounds on heating were determined; however, heating due to externally injected noise could not be completely ruled out. Noise on the RF potential responsible for providing confinement was identified as one source of injected noise. Using the microfabrication technology developed for ion traps, I made a cantilevered micromechanical oscillator and with coworkers demonstrated a method to reduce the kinetic energy of its lowest order mechanical mode via its capacitive coupling to a driven RF resonant circuit. Cooling results from a RF capacitive force, which is phase shifted relative to the cantilever motion. The technique was demonstrated by cooling a 7 kHz fundamental mode from room temperature to 45 K. Ground state cooling of the mechanical modes of motion of harmonically trapped ions is routine; equivalent cooling of a macroscopic harmonic oscillator has not yet been demonstrated. Extension of this method to devices with higher motional frequencies in a cryogenic system, could enable ground state cooling and may prove simpler than related optical experiments. I also discuss an implementation of the semiclassical quantum Fourier transform (QFT) using three beryllium ion qubits. The QFT is a crucial step in a number of quantum algorithms including Shor's algorithm, a quantum approach to integer factorization which is exponentially faster than the fastest known classical factoring algorithm. This demonstration incorporated the key elements of a scalable ion-trap architecture for QIP. 0.1% topic match

[114] High-fidelity quantum control using ion crystals in a penning trap M. Biercuk, ..., and J. Bollinger Quantum Inf. Comput. 2009 - 50 citations - Show abstract - Cite - PDF Abstract: We provide an introduction to the use of ion crystals in a Penning trap [1, 2, 3, 4] forexperiments in quantum information. Macroscopic Penning traps allow for the contain-ment of a few to a few million atomic ions whose internal states may be used in quantuminformation experiments. Ions are laser Doppler cooled [1], and the mutual Coulomb re-pulsion of the ions leads to the formation of crystalline arrays [5, 6, 7, 8]. The structureand dimensionality of the resulting ion crystals may be tuned using a combination ofcontrol laser beams and external potentials [9, 10]. We discuss the use of two-dimensional 9Be+ ion crystals for experimental tests ofquantum control techniques. Our primary qubit is the 124 GHz ground-state electronspin flip transition, which we drive using microwaves [11, 12]. An ion crystal representsa spatial ensemble of qubits, but the effects of inhomogeneities across a typical crystalare small, and as such we treat the ensemble as a single effective spin. We are able toinitialize the qubits in a simple state and perform a projective measurement [1] on thesystem. We demonstrate full control of the qubit Bloch vector, performing arbitrary high-fidelity rotations (τπ ∼200 µs). Randomized Benchmarking [13] demonstrates an errorper gate (a Pauli-randomized π=2 and π pulse pair) of 8±1×10-4. Ramsey interferome-try and spin-locking [14] measurements are used to elucidate the limits of qubit coherencein the system, yielding a typical free-induction decay coherence time of T2 ∼2 ms, and alimiting T1ρ ∼688 ms. These experimental specifications make ion crystals in a Penningtrap ideal candidates for novel experiments in quantum control. As such, we brieflydescribe recent efforts aimed at studying the error-suppressing capabilities of dynamicaldecoupling pulse sequences [15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26], demonstratingan ability to extend qubit coherence and suppress phase errors [11, 12]. We concludewith a discussion of future avenues for experimental exploration, including the use of ad-ditional nuclear-spin-flip transitions for effective multiqubit protocols, the potential forhardware refinements to suppress qubit error rates well-below predicted fault-tolerancethresholds, and possibilities for single-ion addressing useful for the realization of complexentangled states. 0.0% topic match

[129] Theory and application of planar ion traps C. Pearson Journal Not Provided 2006 - 5 citations - Show abstract - Cite Abstract: In this thesis, we investigate a new geometry of Paul trap with electrodes in a plane. These planar ion traps are compatible with modern silicon microfabrication, and can be scaled up to large arrays with multiple trapping zones. We implement these designs on printed circuit boards with macroscopic ions, allowing us to study the traps while avoiding the experimental challenges of atomic ion traps. We discuss the dynamics of ions in the traps using both numerical and analytical means. Scalable traps are of interest to the quantum computing community as a potential implementation of a large scale quantum computer. However, there are concerns about the low trap depth relative to a conventional trap of the same size. We address this in three ways, first by introducing a conductive plane above the trap to increase its depth, then by using a deeper trap with a three dimensional electrode geometry to load the trap, and finally by loading the trap directly while using a buffer gas to slow down energetic ions so that the trap can capture them. Also of concern is the ability of the trap to move ions through arms and intersections. We demonstrate these movement operations, and study properties of the linear trap including the secular frequency and geometric factors between planar and four rod traps. The precision of atomic ion trap experiments makes them sensitive to background gas pressure at levels that are undetectable to conventional gauges. The capacity for integrating circuitry and optical elements with the trap could anticipate complete ion trap experiments performed by a single chip, and a new technology for an integrated pressure gauge would be immensely useful if the pressure detection can shown to be feasible and repeatable. In a point planar trap, we observe ion motion to determine background gas pressure, demonstrating an application that could bring planar ion traps into much wider use. Thesis Supervisor: Isaac L.

[149] Ytterbium ion trapping and microfabrication of ion trap arrays R. C. Sterling Journal Not Provided 2012 - 6 citations - Show abstract - Cite Abstract: Over the past 15 years ion traps have demonstrated all the building blocks required of a quantum computer. Despite this success, trapping ions remains a challenging task, with the requirement for extensive laser systems and vacuum systems to perform operations on only a handful of qubits. To scale these proof of principle experiments into something that can outperform a classical computer requires an advancement in the trap technologies that will allow multiple trapping zones, junctions and utilize scalable fabrication technologies. I will discuss the construction of an ion trapping experiment, focussing on my work towards the laser stabilization and ion trap design but also covering the experimental setup as a whole. The vacuum system that I designed allows the mounting and testing of a variety of ion trap chips, with versatile optical access and a fast turn around time. I will also present the design and fabrication of a microfabricated Y junction and a 2- dimensional ion trap lattice. I achieve a suppression of barrier height and small variation of secular frequency through the Y junction, aiding to the junctions applicability to adiabatic shuttling operations. I also report the design and fabrication of a 2-D ion trap lattice. Such structures have been proposed as a means to implement quantum simulators and to my knowledge is the first microfabricated lattice trap. Electrical testing of the trap structures was undertaken to investigate the breakdown voltage of microfabricated structures with both static and radio frequency voltages. The results from these tests negate the concern over reduced rf voltage breakdown and in fact demonstrates breakdown voltages significantly above that typically required for ion trapping. This may allow ion traps to be designed to operate with higher voltages and greater ion-electrode separations, reducing anomalous heating. Lastly I present my work towards the implementation of magnetic fields gradients and microwaves on chip. This may allow coupling of the ions internal state to its motion using microwaves, thus reducing the requirements for the use of laser systems. 0.0% topic match

[150] Sensitive, 3D micromotion compensation in a surface-electrode ion trap A. Eltony Journal Not Provided 2013 - 4 citations - Show abstract - Cite Abstract: Following successful demonstrations of quantum algorithms and error correction with a handful of trapped ions in a macroscopic, machined Paul trap, there is a growing effort to move towards microfabricated traps with all the electrodes on a single chip. These traps, known as surface-electrode ion traps, are more amenable to being shrunk in size and replicated, or integrated with optical components and electronic devices. However, in the shift towards surface-electrode traps, and as traps are miniaturized in general, laser beams are brought closer to electrode surfaces, exacerbating laser-induced charging. Because of their charge, trapped ions are extremely sensitive to stray charges that accumulate on the trap surface. The DC potentials caused by stray charge displace the ion from the null of the RF trapping field, resulting in a fast, driven motion of the ion (known as micromotion) which hinders quantum operations by broadening transitions and causing decoherence. In a surface trap, micromotion detection is difficult as the laser beams used for measurement typically cannot crash into the trap, obscuring ion offsets out of the trap plane. Existing methods for micromotion detection permit ion positioning accurate to the ground state wavepacket size (of order 10 nm), but cannot identify ion offsets out of the trap plane with the same accuracy. Schemes for sensitive compensation often have restrictive requirements such as access to a narrow atomic transition. We introduce a new approach, which permits out-of-plane micromotion compensation to within 10s of nanometers with minimal overhead. Our technique synchronously detects ion excitation along the trap axes when it is driven by secular-frequency sidebands added to the RF electrodes; the excitation amplitude is proportional to the offset from the RF null. We make a detailed theoretical comparison with other techniques for micromotion compensation and demonstrate our technique experimentally. Acknowledgments A great thanks to Professor Isaac Chuang for giving me the opportunity to work in the Quanta Group and explore this exciting field. His generosity with his time and knowledge have been a huge help to me. Under his guidance, I have learned a great deal about designing and realizing scientific experiments, technical communication, and even management. I have also gained immensely from interactions with Shannon Wang and Peter Herskind, who showed me the ropes of the cryogenic ion trapping experiment and introduced me to the lasers in lab during my first year in the group.

Chuang Bulletin of the American Physical Society 2007 - 58 citations - Show abstract - Cite - PDF Abstract: Quantum simulations of spin systems could enable the solution of problems that otherwise require infeasible classical resources. Such a simulation may be implemented using a well-controlled system of effective spins, such as a two-dimensional lattice of locally interacting ions. We propose here a layered planar rf trap design that can be used to create arbitrary two-dimensional lattices of ions. The design also leads naturally to ease of microfabrication. As a first experimental demonstration, we confine S88r+ ions in a millimeter-scale lattice trap and verify numerical models of the trap by measuring the motional frequencies. We also confine 440 nm diameter charged microspheres and observe ion-ion repulsion between ions in neighboring lattice sites. Our design, when scaled to smaller ion-ion distances, is appropriate for quantum simulation schemes, e.g., that of Porras and Cirac [Phys. Rev. Lett. 92, 207901 (2004)]. We note, however, that in practical realizations of the trap, an increase in the secular frequency with decreasing ion spacing may make a coupling rate that is large relative to the decoherence rate in such a trap difficult to achieve.Quantum simulations of spin systems could enable the solution of problems that otherwise require infeasible classical resources.
