CAS Cold Atom Technology, a Wuhan-based firm affiliated with the Chinese Academy of Sciences (CAS), unveiled what it claims is the world's first dual-core quantum computer, according to a report from state-owned publication Science and Technology Daily. The system, called Hanyuan-2, pairs two independent neutral atom arrays inside a single cabinet-sized machine, totaling 200 qubits built from 100 rubidium-85 and 100 rubidium-87 atoms.
The company said the twin cores can either run in parallel to split workloads or operate in a "one main and one auxiliary" configuration, where the second array handles real-time error correction while the first executes computations. Ge Guiguo, a senior expert at CAS Cold Atom Technology, told Science and Technology Daily that the system represents the first time a quantum processor has moved from single-core to dual-core architecture.
