Chinese Scientists Develop Quantum Computer with 113 Detected Photons

Chinese scientists have developed a quantum computer prototype with 113 detected photons to solve tasks using the classical Gaussian boson sampling (GBS) modeling algorithm.

The researchers said the Jiuzhang 2.0 system can facilitate large-scale GBS septillion times faster than the fastest existing supercomputer and 10 billion times faster than its 76-photon Jiuzhang predecessor.

The researchers were inspired by the Laser (light amplification by stimulated emission of radiation) concept to develop a stimulated squeezed light source with high brightness and concurrent near-unity purity and efficiency for scalable GBS.

They said Jiuzhang 2.0 could potentially be applied in domains like graph theory, machine learning, and quantum chemistry.
