Description
Digital Single Photon Avalanche Diode (SPAD) arrays are widely used in subatomic physics for ionizing radiation detection primarily associated with scintillating materials. They are increasingly used for measuring distances within LIDAR (LIght Detection And Ranging) systems and in a variety of sensors. In quantum applications, Superconducting Nano Single Photon Detector (SNSPD) are primarily used offering high efficiency and very low dark noise. In this talk, we explore the opportunity of using SPADs designed specifically for quantum applications. The requirements are efficiency exceeding 2/3 and dark noise comparable to SNSPD although without having to operate below 4 Kelvin. Can this be done? We will address this question during the talk and speculate about possible future quantum applications of SPADs.
