Repeaterless quantum key distribution with efficient finite-key analysis overcoming the rate-distance limit
The recently proposed Twin Field QKD protocol allows to beat the linear scaling of the key rate with the channel losses. Here, the authors extend it including a full security proof in the finite block size regime, allowing for practically-relevant secure key rates.
