Pan Jianwei and Chen Tengyun of China University of Science and Technology have cooperated with Ma Xiongfeng University of Tsinghua University for the first time in the experiment.
According to CCTV News on February 5th, the relevant research results have been published in the Physics Review Express of the International Academic Journal.
The quantum key distribution is based on the basic principles of quantum mechanics, which can realize theoretically unconditional and secure confidential communication.Model matching the quantum key distribution protocol (MP-QKD) is a new type of measurement equipment proposed by Tsinghua University Ma Xiongfeng Research Group in 2022.The detection event can be used to make a large extent, which can greatly increase the code rate; compared to the double quantum key distribution protocol and phase matching protocol, no complex laser locking technology is required, saving costs and reducing practical application difficultiesAt the same time, it has better anti -interference ability to environmental noise.
Studies have shown that the pattern matching quantum key distribution can achieve long -distance security and code in the condition that no laser lock is locking.The difficulty of implementing the agreement is of great significance to the construction of a quantum communication network in the future.
