摘要:Research efforts have been devoted to quantum standards for optical radiometry at the National Institute of Metrology of China. In the field of single photon metrology, have been established the capabilities including ultra low noise low light power-meter, predictable quantum efficiency detector, single photon detector quantum efficiency calibration method using correlated photons produced from spontaneous parametric down-conversion, few photon sources generated via second harmonic generation, and etc. Will also be discussed self-consistent on-demand single photon source as a long term goal towards the realization of quantum Candela (one of the seven SI base units) and photon number resolving detector based on superconducting transition edge sensor as a key validation device for this purpose.
