On May 13, 2026, China’s University of Science and Technology of China said Jiuzhang 4.0 solved Gaussian boson sampling at a speed 10^54 times faster than the fastest supercomputer.
The prototype uses photonic qubits to control up to 3,050 photons—beyond Jiuzhang 3.0’s 255—and was called a world record in quantum information.
The peer-reviewed results appeared in Nature on May 13, 2026, showing quantum advantage and placing China at the forefront of the quantum-computing race.
