Quantum Enigma Machines and the Locking Capacity of a Quantum Channel by Saikat Guha, Patrick Hayden, Hari Krovi, Seth Lloyd, Cosmo Lupo, Jeffrey H. Shapiro, Masahiro Takeoka, Mark M. Wilde

“…The encoded message is then secure against any measurement that an eavesdropper could perform in an attempt to recover the message, but the protocol does not necessarily meet the composability requirements needed in quantum key distribution applications. …”

Line-of-sight quantum key distribution with differential phase shift keying by Hiroyuki Endo, Toshihiko Sasaki, Masahiro Takeoka, Mikio Fujiwara, Masato Koashi, Masahide Sasaki

“…We provide a security proof for the differential phase shift (DPS) keying scheme in terms of the metric which meets the composability. We investigate numerically the performances of LoS-QKD with DPS keying, including finite-length analysis, showing that our proposed scheme can realize high-speed and long-distance secret key agreement with information-theoretic security.…”
