On November 11th, the research team led by Zhan Mingsheng and Xu Peng from the Innovation Academy for Precision Measurement Science and Technology at the Chinese Academy of Sciences achieved a significant breakthrough in the realm of neutral-atom quantum computing. The team introduced and experimentally validated a novel architecture for atomic quantum computing that leverages fiber arrays. This innovation effectively tackles the challenge of achieving high parallelism, rapid speed, and robust stability in addressing and controlling atomic quantum computing systems simultaneously. The findings of this groundbreaking research have been published in Nature Communications.

According to Xu Peng, the head of the research team, in their prototype system, the team successfully trapped 10 individual atoms in stable optical traps formed by fiber arrays. For the first time, they demonstrated high-fidelity parallel manipulation of "arbitrary single-qubit gates" within a two-dimensional atomic array. Additionally, they clearly observed the Rydberg blockade effect between two atoms—a crucial physical foundation for implementing high-fidelity two-qubit gates.

Xu Peng further elaborated that this architecture has the potential for scalability through channel replication and is compatible with integrated photonic chips. This compatibility offers a promising new avenue for advancing large-scale neutral-atom quantum computing.
