Realization of quantum secure direct communication over 100 km fiber with time-bin and phase quantum states

Abstract Rapid progress has been made in quantum secure direct communication in recent years. For practical application, it is important to improve the performances, such as the secure information rate and the communication distance. In this paper, we report an elaborate physical system design and p...
