Photons, the individual quanta of the light field, are what the science of quantum photonics is dedicatedly investigating. The manipulation and coherent control of photons in quantum photonics enables the exploration of various quantum phenomena of high fundamental interest. In the meantime, due to the fast speed and a lack of the interaction with the environment, photons are now regarded as a promising platform for the emerging quantum information processing (QIP) studies. Therefore, there is a growing number of works on quantum computing, quantum communication, and quantum metrology that are solidly based on the techniques of quantum photonics.

量子光子学：特性介绍

光子，光场的单个量子，是量子光子学专门研究的对象。量子光子学中光子的操纵和相干控制使人们能够探索各种具有重要基础意义的量子现象。同时，由于速度快且缺乏与环境的相互作用，光子现在被视为新兴量子信息处理（QIP）研究的有前途的平台。因此，越来越多的量子计算、量子通信和量子计量方面的工作都牢固地基于量子光子学技术。
