A comprehensive research review published on arXiv by researchers at Information Engineering University (arXiv:2608.05010) provides a detailed panoramic analysis of global neutral-atom quantum computing progress from 2000 through mid-2026. While tracking international milestones across leaders such as QuEra, Atom Computing, and Pasqal, the paper offers rare and granular visibility into China’s rapidly accelerating domestic neutral-atom ecosystem across both top academic laboratories and a nascent commercial startup corridor.
The survey indicates that while Western efforts have pushed ahead in multi-round active quantum error correction (QEC) demonstrations and topological codes, Chinese research teams have achieved internationally leading performance in core physical parameters—notably two-qubit gate fidelities exceeding 99.8%, constant-time parallel array rearrangements, and metasurface-generated tweezer arrays trapping over 11,000 atoms. Simultaneously, several domestic startups have transitioned from laboratory prototypes into deployable, commercial-grade hardware platforms.

Academic Foundations: World Records in Array Size, Speed, and Gate Fidelity
China’s academic institutions have rapidly established world-class benchmarks in atom trapping, optical manipulation, and high-fidelity Rydberg gate implementations:
- Constant-Time AI Rearrangements at USTC: In August 2025, Pan Jianwei’s group at the University of Science and Technology of China (USTC) used a high-speed spatial light modulator (SLM) driven by artificial intelligence to implement an array-scale-independent, constant-time atom rearrangement protocol. The team assembled defect-free 2D and 3D arrays of 2,024 atoms within 60 milliseconds. Crucially, the system demonstrated a two-qubit gate fidelity of 99.84%, single-qubit fidelity of 99.97%, and readout fidelity of 99.92%—rivaling the world’s best physical gate benchmarks. In 2026, the team demonstrated mid-circuit non-destructive auxiliary readouts and feedback control (arXiv:2603.01612).
- 11,000-Atom Trapping via External Metasurfaces: Addressing the power efficiency and optical aperture constraints of conventional microscope objectives, Zhai Hui’s group at Tsinghua University demonstrated the stable trapping of an average of 11,022 neutral atoms across an 18,225-site optical grid (135 × 135) using a 2-cm-diameter planar metasurface chip positioned outside the vacuum chamber (arXiv:2606.02715). Paired with their “Zhui Feng” graph neural network rearrangement algorithm, the team compressed 10,000-atom-scale sorting times to under 20 milliseconds.
- NP Optimization and Fiber-Array Architectures: Fudan University has established specialized quantum annealing architectures, utilizing parallel atom transport with sub-1% loss rates to streamline circuit depths for complex NP-hard computational problems, supported by automated AI calibration and 1,000-atom hardware. Meanwhile, the Innovation Academy for Precision Measurement Science and Technology (APM, CAS) in Wuhan has pioneered heteronuclear 87Rb–85Rb entangling gates and developed a compact fiber-array architecture using fiber-end microlenses for individual atom addressing.
Commercialization Landscape: Cabinet-Scale Systems and Ytterbium Platforms
China’s commercial neutral-atom landscape has rapidly organized around dedicated full-system startups backed by domestic venture capital and supply-chain initiatives:
- Zhongke Kuyuan (Wuhan): The pioneer of engineering-grade commercial systems in China, Zhongke Kuyuan delivered two experimental platforms based on its Hanyuan 1 architecture in early 2025. In 2026, the company launched Hanyuan 2, a dual-cavity, dual-core commercial machine supporting over 500 optical tweezers with a coherence time (T2) exceeding 300 ms, single-qubit fidelity above 99.9%, and two-qubit fidelity above 99%. Operating at room temperature within standard server racks drawing under 7 kW, the system boasts an 80%+ domestic component localization rate. The company is actively building its 1,000-qubit Hanyuan 3 platform.
- Taiyi Liangsheng (Shanghai): Established in early 2026, Taiyi Liangsheng is China’s first commercial venture dedicated to alkaline-earth-metal ytterbium (171Yb) platforms. Leveraging nuclear-spin clock states for longer coherence times, telecom-band optical interconnects, and fast multi-qubit gates, the company closed over ¥400 million (~$56 million USD) across Angel and Pre-A financing rounds to deliver logical qubit demonstrations.
- Liangyi Wanxiang (Beijing): Founded in 2024 by specialists in high-speed optical feedback and Rydberg control, Liangyi Wanxiang demonstrated a 500+ atom tweezer platform with two-qubit gate fidelities exceeding 99.5%, collaborating with domestic foundries on custom optical integrated circuits targeting a 1,000-qubit fault-tolerant platform by 2027.
- Chip-Scale Metasurface Integration: Startup Zhongqi Wuliang partnered with flat-optics specialist Xuanxiang Technology to validate a million-tweezer metasurface optical chip, seeking an industrial pathway to mass-manufacture high-density trap arrays that bypass conventional spatial light modulator bottlenecks.
Strategic Analysis: Where China Leads, and Where Gaps Remain
The review concludes with a balanced assessment of the global competitive standing. China has closed the physical capability gap with the West in hardware scaling and raw physical gate metrics—matching or exceeding international peers in array dimensions, rearrangement latency, and raw gate fidelity. Domestic supply chains are also rapidly maturing across laser systems, vacuum chambers, high-numerical-aperture lenses, and control electronics.
However, the authors emphasize that China still lags behind leading U.S. programs in system-level quantum error correction and practical algorithmic fault tolerance. While U.S. ventures have demonstrated transversal logical gates across 48 logical qubits (QuEra/Harvard), multi-round continuous syndrome extraction on toric codes (Atom Computing), and precompiled logical Shor’s algorithm implementations (Infleqtion), China’s ecosystem is only now advancing from mid-circuit measurement primitives into active, multi-round QEC cycles. Bridging the gap between physical gate demonstrations and continuous, fault-tolerant logical computation remains the primary objective for China’s neutral-atom roadmap heading into 2027.
