China's 'Hanyuan-2' has emerged as the world's first dual-core quantum computer, boasting 200 qubits and remarkable power efficiency, although performance benchmarks have not yet been released. On May 7, 2026, Zhongke Kuyuan Technology, a Wuhan-based company under the Chinese Academy of Sciences, announced the ' Hanyuan-2, ' a dual-core neutral-atom quantum computer touted as the world's first. This follows the company's launch of the 'Hanyuan-1,' China's first commercial neutral-atom quantum computer, in 2024, as reported by the Chinese state-run media outlet Science and Technology Daily.

The enclosure features a standard rack-mount integrated design, operates with only a small laser cooling system, and can be quickly installed in a normal indoor environment without requiring a complex cryogenic cooling environment. The overall power consumption is said to be less than 7kW, which is expected to significantly reduce the application hurdles and introduction costs of quantum computing technology. According to Ge Guiguo, a senior researcher at Zhongke Kuyuan, a Chinese startup specializing in quantum computing technology, this is the world's first transition from a 'single-core' to a 'dual-core' architecture for a quantum processor, representing a unique breakthrough in the core architecture of quantum computing. Both cores are independent, fully neutral atom qubit arrays. In addition to a 'parallel computing' mode that shares the workload, they can also operate in a 'main + auxiliary' mode where the first array performs calculations
