SYSU team develops unconventional entangled quantum light sources with near-unity fidelity
A study led by Professors Xuehua Wang and Jin Liu from the School of Physics at Sun Yat-sen University (SYSU) presented a novel cavity-induced spontaneous two-photon emission (STPE) scheme, taking the lead internationally in achieving spontaneous two-photon emission with intensity comparable to that of single-photon emission. Published in Nature on July 9, 2025, this work enables the generation...
