Insight on future quantum networks

摘要

In the past few years, significant improvements have been achieved in quantum communication. To extend the communication range, however, a new technology based on quantum memories needs to be developed. In PNAS, Bao et al. (1) give an example of the building blocks of the quantum communication networks we may expect to see in the future. These complex systems will be built on the basic ingredients of quantum state teleportation and quantum memories and will expand over relatively large distances.
