China Telecom Deploys a 2,682-Photon Quantum Computer to Provide Commercial Cloud Services Worldwide

China Telecom Quantum Group announced on June 29 the deployment of the Tianyan-P2000, a 2,682-photon photonic quantum computer based on the Jiuzhang 4.0 architecture, integrated into its Tianyan quantum cloud infrastructure and offering commercial quantum computing services globally. The system operates at room temperature, complementing China Telecom's existing superconducting quantum infrastructure, and targets specific problem categories where photonic approaches have demonstrated quantum advantage including graph analysis, drug discovery, spectral computation and machine vision models.

The 2,682-photon count is a specific and significant number in the context of Gaussian boson sampling, the computational task Jiuzhang-class systems are designed to perform. Boson sampling has been one of the clearest demonstrations of quantum computational advantage over classical computers for specific tasks, and the Jiuzhang series has been progressively scaling toward problem sizes where classical simulation becomes demonstrably infeasible. The Jiuzhang 4.0 represents the latest generation of this architecture and the transition from laboratory demonstrations to a commercial cloud platform integrated into a major telco's infrastructure is a genuinely different kind of milestone from academic publications.

China Telecom providing global access to this system through cloud services means international researchers and enterprises can use Jiuzhang 4.0-class photonic quantum computing for the first time. The system's room temperature operation and specialised applications for graph problems and machine vision sit alongside rather than competing with superconducting gate-model systems, reflecting the broader industry consensus that multiple quantum modalities will coexist serving different workload types rather than one approach winning outright.
