China the first scientist to realize quantum teleportation of quantum transport in Anhui Hefei intercity proved feasible: the realization of quantum teleportation in September 20, Beijing City optical network (Yu Siluan, Yang Baoguo) quantum teleportation is an important means of communication transmission of quantum state, generally speaking, is the quantum information encoding in photons from a a location remote transmission to another place. The day before, cooperation of University of Science & Technology China professor Pan Jianwei, Zhang Qiang and other relevant units in the Hefei metropolitan area, quantum communication experiment online for the first time quantum state quantum entanglement distribution between the independent source of teleportation in advance. The results of the study published online September 19th in the British "nature photonics" on ·. Quantum and Canadian research team published on the same day the teleportation experiment results. These two independent studies have shown that the quantum teleportation of the inter city network is technically feasible, which lays a solid foundation for the future construction of scalable quantum networks. Zhang Qiang, quantum communication mainly through the existing quantum key for classical information transmission is encrypted, along with the development of technology, quantum secure communication will eventually realize the transmission of quantum information, quantum teleportation is expected to safety and strength of Internet connection is greatly improved through the optical fiber network. However, it is necessary to use the optical fiber network to carry out the long distance quantum teleportation, and the light source of the two light sources will not be different after long distance transmission.相关的主题文章:
