Benefiting from quantum superposition and quantum entanglement, quantum computing offers significant computational speedup over classical counterparts for certain classes of complex problems. Ion trap is one of the leading physical platforms for realizing universal quantum computing. High-fidelity elementary quantum operations above the fault-tolerant threshold in small-scale systems have been demonstrated, such as state preparation and measurement, and universal quantum gates. Scaling trapped-ion systems to larger qubit counts while maintaining high fidelity is a central challenge and a key research direction toward practical quantum computing. This article begins with an overview of the principles of quantum parallel computing and historical development of quantum computing, which is followed by a comprehensive discussion of the foundational concepts and recent progress in ion trap quantum computing from the perspectives of hardware architecture and computing principles. Then, it focuses on the critical issue of scaling, reviewing mainstream approaches such as ion transport and ion-photon quantum networks, along with their current limitations. Furthermore, it explores emerging strategies for scaling, including the development of two-dimensional ion crystal. Finally, the article provides recommendations to accelerate the advancement of quantum computing from both technological and industrial perspectives.

351(6277): 1068-1070., articleTitle=Realization of a scalable shor algorithm, refAbstract=Certain algorithms for quantum computers are able to outperform their classical counterparts. In 1994, Peter Shor came up with a quantum algorithm that calculates the prime factors of a large number vastly more efficiently than a classical computer. For general scalability of such algorithms, hardware, quantum error correction, and the algorithmic realization itself need to be extensible. Here we present the realization of a scalable Shor algorithm, as proposed by Kitaev. We factor the number 15 by effectively employing and controlling seven qubits and four "cache qubits" and by implementing generalized arithmetic operations, known as modular multipliers. This algorithm has been realized scalably within an ion-trap quantum computer and returns the correct factors with a confidence level exceeding 99%.

High-fidelity entangling gates in neutral atoms have seen remarkable advancement recently. A full understanding of error sources and their respective contributions to gate infidelity will enable the prediction of fundamental limits on quantum gates in neutral atom platforms with realistic experimental constraints. In this work, we implement the time-optimal Rydberg controlled-Z (CZ) gate, design a circuit to benchmark its fidelity, and achieve a fidelity, averaged over symmetric input states, of 0.9971(5), downward corrected for leakage error, which together with our recent work [Nature 634, 321–327 (2024)] forms a new state of the art for neutral atoms. The remaining infidelity is explained by an error model, consistent with our experimental results over a range of gate speeds, with varying contributions from different error sources. Further, we develop a fidelity response theory to efficiently predict infidelity from laser noise with nontrivial power spectral densities and derive scaling laws of infidelity with gate speed. Besides its capability of predicting gate fidelity, we also utilize the fidelity response theory to compare and optimize gate protocols, to learn laser frequency noise, and to study the noise response for quantum simulation tasks. Finally, we predict that a CZ gate fidelity of ≳0.999 is feasible with realistic experimental upgrades.), Reference(id=1242115044872356462, tenantId=1146029695717560320, journalId=1146032081894723586, articleId=1218251590138511751, doi=10.1038/s41586-023-06927-3, pmid=null, pmcid=null, year=2024, volume=626, issue=7997, pageStart=58, pageEnd=65, url=null, language=null, rfNumber=[18], rfOrder=17, authorNames=Bluvstein D, Evered S J, Geim A A, journalName=Nature, refType=null, unstructuredReference=

626(7997): 58-65., articleTitle=Logical quantum processor based on reconfigurable atom arrays, refAbstract=Suppressing errors is the central challenge for useful quantum computing1, requiring quantum error correction (QEC)2–6for large-scale processing. However, the overhead in the realization of error-corrected ‘logical’ qubits, in which information is encoded across many physical qubits for redundancy2–4, poses substantial challenges to large-scale logical quantum computing. Here we report the realization of a programmable quantum processor based on encoded logical qubits operating with up to 280 physical qubits. Using logical-level control and a zoned architecture in reconfigurable neutral-atom arrays7, our system combines high two-qubit gate fidelities8, arbitrary connectivity7,9, as well as fully programmable single-qubit rotations and mid-circuit readout10–15. Operating this logical processor with various types of encoding, we demonstrate improvement of a two-qubit logic gate by scaling surface-code6distance fromd = 3 tod = 7, preparation of colour-code qubits with break-even fidelities5, fault-tolerant creation of logical Greenberger–Horne–Zeilinger (GHZ) states and feedforward entanglement teleportation, as well as operation of 40 colour-code qubits. Finally, using 3D [[8,3,2]] code blocks16,17, we realize computationally complex sampling circuits18with up to 48 logical qubits entangled with hypercube connectivity19with 228 logical two-qubit gates and 48 logical CCZ gates20. We find that this logical encoding substantially improves algorithmic performance with error detection, outperforming physical-qubit fidelities at both cross-entropy benchmarking and quantum simulations of fast scrambling21,22. These results herald the advent of early error-corrected quantum computation and chart a path towards large-scale logical processors.), Reference(id=1242115044943659631, tenantId=1146029695717560320, journalId=1146032081894723586, articleId=1218251590138511751, doi=null, pmid=null, pmcid=null, year=2025, volume=134, issue=9, pageStart=null, pageEnd=null, url=null, language=null, rfNumber=[19], rfOrder=18, authorNames=Gao D X, Fan D J, Zha C, journalName=Physical Review Letters, refType=null, unstructuredReference=

Until now, the longest coherence-time of a single qubit was reported as 660 s in a single Yb ion-qubit through the technical developments of sympathetic cooling and dynamical decoupling pulses, which addressed heating-induced detection inefficiency and magnetic field fluctuations. However, it was not clear what prohibited further enhancement. Here, we identify and suppress the limiting factors, which are the remaining magnetic-field fluctuations, frequency instability and leakage of the microwave reference-oscillator. Then, we observe the coherence time of around 5500 s for the Yb ion-qubit, which is the time constant of the exponential decay fit from the measurements up to 960 s. We also systematically study the decoherence process of the quantum memory by using quantum process tomography and analyze the results by applying recently developed resource theories of quantum memory and coherence. Our experimental demonstration will accelerate practical applications of quantum memories for various quantum information processing, especially in the noisy-intermediate-scale quantum regime.), Reference(id=1242115046877233784, tenantId=1146029695717560320, journalId=1146032081894723586, articleId=1218251590138511751, doi=null, pmid=null, pmcid=null, year=1997, volume=null, issue=null, pageStart=657, pageEnd=null, url=null, language=null, rfNumber=[27], rfOrder=26, authorNames=DiVincenzo D P, journalName=Topics in quantum computers, refType=null, unstructuredReference=

10.22331/q-2024-11-07-1516., articleTitle=Benchmarking a trapped-ion quantum computer with 30 qubits, refAbstract=Quantum computers are rapidly becoming more capable, with dramatic increases in both qubit count \\cite{kim2023evidence} and quality \\cite{moses2023race}. Among different hardware approaches, trapped-ion quantum processors are a leading technology for quantum computing, with established high-fidelity operations and architectures with promising scaling. Here, we demonstrate and thoroughly benchmark the IonQ Forte system: configured as a single-chain 30-qubit trapped-ion quantum computer with all-to-all operations. We assess the performance of our quantum computer operation at the component level via direct randomized benchmarking (DRB) across all 30 choose 2 = 435 gate pairs. We then show the results of application-oriented \\cite{IonQ_AQ20_2022}\\cite{qedcPeerReviewed} benchmarks and show that the system passes the suite of algorithmic qubit (AQ) benchmarks up to #AQ 29. Finally, we use our component-level benchmarking to build a system-level model to predict the application benchmarking data through direct simulation. While we find that the system-level model correlates with the experiment in predicting application circuit performance, we note quantitative discrepancies indicating significant out-of-model errors, leading to higher predicted performance than what is observed. This highlights that as quantum computers move toward larger and higher-quality devices, characterization becomes more challenging, suggesting future work required to push performance further.), Reference(id=1242115047967752840, tenantId=1146029695717560320, journalId=1146032081894723586, articleId=1218251590138511751, doi=null, pmid=null, pmcid=null, year=2022, volume=106, issue=6, pageStart=null, pageEnd=null, url=null, language=null, rfNumber=[43], rfOrder=42, authorNames=Yao R, Lian W Q, Wu Y K, journalName=Physical Review A, refType=null, unstructuredReference=

Nature,

638(8050): 383-388., articleTitle=Distributed quantum computing across an optical network link, refAbstract=Distributed quantum computing (DQC) combines the computing power of multiple networked quantum processing modules, ideally enabling the execution of large quantum circuits without compromising performance or qubit connectivity1,2. Photonic networks are well suited as a versatile and reconfigurable interconnect layer for DQC; remote entanglement shared between matter qubits across the network enables all-to-all logical connectivity through quantum gate teleportation (QGT)3,4. For a scalable DQC architecture, the QGT implementation must be deterministic and repeatable; until now, no demonstration has satisfied these requirements. Here we experimentally demonstrate the distribution of quantum computations between two photonically interconnected trapped-ion modules. The modules, separated by about two metres, each contain dedicated network and circuit qubits. By using heralded remote entanglement between the network qubits, we deterministically teleport a controlled-Z (CZ) gate between two circuit qubits in separate modules, achieving 86% fidelity. We then execute Grover’s search algorithm5—to our knowledge, the first implementation of a distributed quantum algorithm comprising several non-local two-qubit gates—and measure a 71% success rate. Furthermore, we implement distributed iSWAP and SWAP circuits, compiled with two and three instances of QGT, respectively, demonstrating the ability to distribute arbitrary two-qubit operations6. As photons can be interfaced with a variety of systems, the versatile DQC architecture demonstrated here provides a viable pathway towards large-scale quantum computing for a range of physical platforms.), Reference(id=1242115048538178193, tenantId=1146029695717560320, journalId=1146032081894723586, articleId=1218251590138511751, doi=null, pmid=null, pmcid=null, year=2020, volume=124, issue=11, pageStart=null, pageEnd=null, url=null, language=null, rfNumber=[51], rfOrder=50, authorNames=Stephenson L J, Nadlinger D P, Nichol B C, journalName=Physical Review Letters, refType=null, unstructuredReference=
