China continues to lead the quantum computing race, exemplified by its latest achievement – the development of the “Jiuzhang 3.0” quantum computer prototype. Led by quantum physicist Pan Jianwei, the research team achieved a groundbreaking feat with 255 detected photons, making computing 10 quadrillion times faster in solving Gaussian boson sampling (GBS) problems than the world’s fastest supercomputers. Capitalizing on innovations like superconducting nanowire single-photon detection, “Jiuzhang 3.0” outpaces its predecessor by a million times.
