Proof-of-principle experimental demonstration of twin-field quantum key distribution over optical channels with asymmetric losses
Abstract Twin-field (TF) quantum key distribution (QKD) is highly attractive because it can beat the fundamental limit of secret key rate for point-to-point QKD without quantum repeaters. Many theoretical and experimental studies have shown the superiority of TFQKD in long-distance communication. Al...
