China's quantum computing ecosystem shows mixed progress in 2026. USTC's Zuchongzhi 3 (66 superconducting qubits) achieved quantum supremacy on random circuit sampling (similar to Google Sycamore in 2019, but with ~1,000x faster sampling due to improvements). Origin Quantum's Wuyuan (72 qubits) demonstrated hybrid quantum-classical optimization for logistics routing (DHL China pilot). Alibaba Quantum Lab quietly dissolved - team reorganized into DAMO Academy general AI research. CASIC's trapped ion quantum computer (30 qubits) achieved 99.3% gate fidelity. Key bottleneck: quantum error correction remains at 3-5 logical qubits, far from the 1,000+ needed for useful computation. China leads in photonic quantum computing (Jiuzhang 3, 255 detected photons) but practical application remains elusive. Government QKD infrastructure (Beijing-Shanghai quantum backbone) is the most deployed globally.
