Tomography increases key rates of quantum-key-distribution protocols
Shun Watanabe, Ryutaroh Matsumoto, Tomohiko Uyematsu
We construct a practically implementable classical processing for the BB84 protocol and the six-state protocol that fully utilizes the accurate channel estimation method, which is…

Key rate available from mismatched mesurements in the BB84 protocol and the uncertainty principle
Ryutaroh Matsumoto, Shun Watanabe
We consider the mismatched measurements in the BB84 quantum key distribution protocol, in which measuring bases are different from transmitting bases. We give a lower bound on the…
