Quantum Key Distribution using Two Coherent States of Light and their Superposition
Y. Nambu, A. Tomita, Y. Chiba-Kohno +1
Quantum mechanical complementarity ensures the security of the key-distribution scheme reported by Brassard and Bennet in 1984 (BB84), but does not prohibit use of multi-photons as…
