英文摘要：

The single photon detector based on quantum dots（QD） is widely researched due to its advantages such as the potential of single photon detection under room temperature, the ability to maintain the integrity of the detected signal, high theoretical quantum efficiency and the low working voltage. In this paper, three different types of single photon detectors based on quantum dots and their working principles are reviewed. Also discussed are the parameters and characteristics of the detectors. The excellent performance of self-assembly quantum-dot-based single photon detector is explained.
