Centennial Nobel
Research-Grade Photonic Quantum Computer
The Jiuzhang Research-Grade Photonic Quantum Computer integrates the high scalability of time-domain encoding with the high efficiency and strong connectivity of spatial encoding. By engineering novel high-performance quantum light sources and combining ultra-large-scale spatial-temporal multiplexed programmable photonic networks with high-detection-efficiency Superconducting Nanowire Single-Photon Detectors (SNSPDs), this system achieves over 1024 fully-connected input modes and enables the preparation and control of 2,000 to 3,000 photons. In Gaussian Boson Sampling (GBS) tasks, its computational speed exceeds that of classical supercomputers by more than 10^30 times, demonstrating quantum computational advantage. Furthermore, the system comes equipped with intuitive quantum hardware control software, empowering users to efficiently harness photonic quantum computing power and accelerate the solution of specific real-world problems.
