In view of the current network security situation, the basic principles and implementation method of quantum cryptography are studied.Considering the present situation of quantum cryptography communication technology and launch vehicle range, a network scheme is designed based on quantum cryptography communication network, and several miniature tests are carried out.From the results of the validation, network performance test results can meet communication support requirements of the rocket launch test in launch vehicle range, different types of information transmission is normal, and the quantum key technical indicators meet the requirements of the equipment.So the network scheme is a feasible solution.

The precise quantum control of single photons, together with the intrinsic advantage of being mobile make optical quantum system ideally suited for delegated quantum information tasks, reaching from well-established quantum cryptography to quantum clouds and quantum computer networks. Here I present that the exploit of quantum photonics allows for a variety of quantum-enhanced data security for quantum and classical computers. The latter is based on feasible hybrid classical-quantum technology, which shows promising new applications of readily available quantum photonics technology for complex data processing. As outlook I will discuss technological challenges for the scale up of photonic quantum computers, and our group’s current work for addressing some of those.
