USTC quantum groups (Jiuzhang / Zuchongzhi)
Scientific anchor of the Hefei cluster and the lineage behind spinouts Origin Quantum, QuantumCTek, and CIQTEK. Jiuzhang 4.0 (Nature, May 2026) is a Gaussian boson sampling result — 1,024 squeezed inputs, 8,176 modes, up to 3,050 photon detections were lab-asserted — and advantage claims are contested. Zuchongzhi 3.0/3.2 (2025) is a ~105–107 qubit superconducting research system; a surface-code distance-7 logical qubit below threshold was reported in December 2025. Peer-reviewed research, not a product.
Reported Zuchongzhi ~105–107 superconducting qubits (2025 research). Jiuzhang 4.0 is boson sampling, not a gate-model QPU
