Our country's research team has proposed a new architecture for atomic quantum computing, achieving fast and precise control of individual atoms.

The Precision Measurement Science and Technology Innovation Research Institute of the Chinese Academy of Sciences has recently made significant progress in the field of neutral atom quantum computing. The team led by researchers Zhang Mingsheng and Xu Peng has innovatively proposed and experimentally verified a new architecture for atomic quantum computing based on fiber optic arrays, solving the challenge of achieving high parallelism, high speed, and high stability in addressing and controlling atomic quantum computing simultaneously. The related achievements have been published in "Nature Communications." Research team leader, researcher Xu Peng, introduced that in the prototype system, the team stably trapped 10 single atoms in optical traps formed by the fiber optic array, demonstrating high-fidelity "arbitrary single qubit gate" parallel manipulation in a two-dimensional atomic array for the first time, and clearly observed the Rydberg blockade effect of two atoms - which is the key physical foundation for achieving high-fidelity two-qubit gates. "This architecture can be scaled up by duplicating channels, and is compatible with integrated photon chips, providing a new path towards large-scale neutral atom quantum computing," Xu Peng said.
