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.
Key facts
- 200 qubits places Hanyaun-2 well behind the West’s leading neutral atom systems
- Hanyuan-2 follows the delivery of the company's first-generation system, Hanyuan-1, though technical specifications for that machine are also limited
- 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
- Crucially, both these Western firms have published metrics like gate fidelity, coherence time, and error rate data for their systems, while CAS Cold Atom Technology has disclosed none
Summary
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. Hanyuan-2 is built on neutral atom technology, which traps uncharged atoms using laser arrays to cool and manipulate individual neutral atoms as qubits. 200 qubits places Hanyaun-2 well behind the West’s leading neutral atom systems. Crucially, both these Western firms have published metrics like gate fidelity, coherence time, and error rate data for their systems, while CAS Cold Atom Technology has disclosed none of these metrics for Hanyuan-2.
