China unveiled on Thursday the country's first dual-core neutral atomic quantum computer, the "Hanyuan-2," marking a new stage for the country's neutral atomic quantum computing technology, transitioning from the earlier single-core era to dual-core collaboration.
The research and development effort is led by the Chinese Academy of Sciences, in collaboration with Wuhan University, Huazhong University of Science and Technology, and the Wuhan Institute of Quantum Technology.
Compared with Hanyuan-1, a 100-qubit neutral-atom quantum computing system, Hanyuan-2 features a 200-qubit dual-core system that enables computation and real-time error correction to be performed simultaneously.
Hanyuan-2 also delivers major breakthroughs over Hanyuan-1, boosting atomic manipulation accuracy from 90 percent to 99 percent and extending atomic stable survival time from 20 seconds to more than 100 seconds.
In addition, the system consumes under seven kilowatts of power and eliminates the need for cryogenic cooling, allowing reliable operation in standard laboratory environments.
The research and development team has also built an end-to-end production capability, covering the full value chain from chip manufacturing, packaging, and testing to laser modulation and phase-noise suppression, enabling domestic production of key core components.
