On October 11th, reporters learned from the Anhui Quantum Information Engineering Technology Research Center that China has achieved the mass production of the world's first four-channel ultra-low noise semiconductor single-photon detector. This device has set world records in several key indicators such as detection efficiency, dark noise level, and integration level, marking China's single-photon detection technology entering a leading stage, and can provide independently controllable and performance-leading core components for applications such as quantum communication, single-photon radar, biological fluorescence imaging, deep space laser ranging, and single-photon imaging
