Overview
- CAS Cold Atom Technology introduced Hanyuan-2, a 200-qubit system that uses neutral atoms and a dual-core processor architecture.
- The machine contains two arrays built from 100 rubidium‑85 atoms and 100 rubidium‑87 atoms that can run in parallel or assign one array to assist with error checks.
- The company says the cabinet-size unit draws under 7 kW and relies on laser cooling, which avoids the ultra‑low‑temperature refrigerators common in many quantum setups.
- State media labeled it the first dual‑core quantum processor, yet the team has released no gate fidelity, coherence time, or error rate data and no peer‑reviewed paper.
- The firm frames the design for near‑term industrial use after early Hanyuan‑1 contracts, aligning with a wider move toward mid‑scale machines over massive qubit counts.
