Chinese scientists have made a major stride in quantum physics, unveiling the world’s largest atom array designed for quantum computing.

A research team led by physicist Pan Jianwei at the University of Science and Technology of China has developed a system capable of creating atom arrays 10 times larger than previous platforms. According to Chinese media reports, this breakthrough could eventually be scaled up to tens of thousands of quanta building blocks, marking a significant leap in computational efficiency.

At the core of the achievement lies an AI-powered system that can arrange over 2,000 rubidium atoms—each functioning as a qubit—into flawless two- and three-dimensional patterns in just 60 milliseconds. This was accomplished using a high-speed spatial light modulator that shapes laser beams to trap and reorganize atoms with remarkable precision.

Published in Physical Review Letters, the study highlights how neutral atom quantum processors are emerging as one of the most promising architectures for large-scale quantum computing [1]. The team introduced a new theoretical framework to balance readout fidelity with atomic retention, while also proposing a performance benchmark called the quantum circuit iteration rate (qCIR).

The system’s accuracy is among the best in the world, achieving 99.97% for single-qubit operations, 99.5% for two-qubit operations, and 99.92% for qubit state detection.

By demonstrating the ability to build a perfect array of 2,024 rubidium atoms in record time, the Chinese team has set a new benchmark in quantum hardware development—one that could bring the world closer to practical, large-scale quantum computing.
