Beating direct transmission bounds for quantum key distribution with a multiple quantum memory station
Róbert Trényi, Norbert Lütkenhaus
Overcoming repeaterless bounds for the secret key rate capacity of quantum key distribution protocols is still a challenge with current technology. D. Luong et al. [Applied Physics…

Beating the repeaterless bound with adaptive measurement-device-independent quantum key distribution
Róbert Trényi, Koji Azuma, Marcos Curty
Surpassing the repeaterless bound is a crucial task on the way towards realizing long-distance quantum key distribution. In this paper, we focus on the protocol proposed by Azuma e…
