Long-distance high-throughput quantum secure direct communication

Abstract:

Quantum secure direct communication transmits information directly through quantum channels. It is witnessing a transformation from a mere theoretical scheme to a fully developed practical protocol. Central to this is to prolong its transmission distance and increase its capacity. Here we describe the developments in these two directions.
