摘要：

A photon number resolving detector (PNRD) is the basic device for many optics applications, especially for developing optical quantum computer. The implementation of universal nonlinear quantum gates typically requires high quantum efficiency and a wide dynamic range up to a few tens of photons. We have developed a charge integration photon detector (CIPD) as a PNRD with a quantum efficiency of 80% and multiphoton measuring over ten photons at telecom wavelengths. This detector has a signal-to-noise ratio of 3 and operates at 40 Hz at present. In this paper, we introduce the principle of our CIPD and report the capability of detecting different types of photon statistics with a high linearity to incident photon numbers.
