Beating the Fundamental Rate-Distance Limit in a Proof-of-Principle Quantum Key Distribution System

With the help of quantum key distribution (QKD), two distant peers are able to share information-theoretical secure key bits. Increasing the key rate is ultimately significant for the applications of QKD in the lossy channel. However, it has been proven that there is a fundamental rate-distance limi...
