Two-Photon Interference for Quantum Cryptography with a Non-Maximally Entangled Photon Pair
Kaoru Shimizu, Hiroki Takesue, Kiyoshi Tamaki · 2009
This paper proposes a novel scheme of quantum cryptography with the two-photon interference of a non-maximally entangled photon pair. The security is based on the impossibility of the local unitary transformation between the certain non-maximally entangled states.
