Review maps China's fast-growing neutral atom quantum computing scene

[Carol_83]

China's neutral atom quantum computing sector has grown quickly, according to a new review. Quantum Computing Report summarises an arXiv review by researchers at China's Information Engineering University that covers the field from 2000 to mid-2026, with a focus on China

Academic groups have produced some eye catching results. A USTC team led by Pan Jianwei assembled defect free arrays of 2,024 atoms in 60 milliseconds, with fidelities of 99.84 percent for two qubit gates, 99.97 percent for single qubit gates and 99.92 percent for readout. Tsinghua's group led by Zhai Hui trapped an average of 11,022 atoms on a grid of 18,225 sites, and its neural network can rearrange arrays of over 10,000 atoms in under 20 milliseconds

Companies are moving fast too. Zhongke Kuyuan's Hanyuan 2 has more than 500 optical tweezers, coherence times above 300 milliseconds, single qubit fidelity above 99.9 percent and two qubit fidelity of 99 percent. It draws less than 7 kilowatts and uses over 80 percent domestic parts, with a 1,000 qubit Hanyuan 3 in development. Liangyi Wanxiang reports a 500 atom array and aims for an error corrected system with more than 1,000 qubits by 2027

Quantum Computing Report's assessment is that China matches the world's best on physical measures such as array size, rearrangement speed and fidelity. It still trails US groups such as QuEra and Harvard, Atom Computing and Infleqtion on system level error correction

Neutral atoms have become one of the most exciting platforms, and China is clearly a serious player. Big arrays are impressive, but logical qubits are what count in the end. Many of these numbers are company claims or targets, so a little caution is wise

Who is leading the neutral atom race right now? And is China close to catching up on error correction?

Review papers are a good way to see the whole landscape at once. The comparison with US groups is useful. Healthy competition pushes everyone
