About
Jiuzhang Quantum Technology is a Chinese photonic quantum computing company affiliated with Tsinghua University. It builds Gaussian boson sampling (GBS) photonic processors. In May 2026, Jiuzhang Quantum published Jiuzhang 4.0 in Nature, a programmable photonic processor that generates 1,024 squeezed states across 8,176 optical modes, detects up to 3,050 photons, and completes photon sampling tasks in 25.6 microseconds. Classically simulating an equivalent computation on EI Capitan, the world's most powerful classical supercomputer, would take an estimated 10^42 years. The result stands as one of the strongest quantum advantage demonstrations to date.
