Semiquantum Key Distribution Using Entangled States
Semiquantum Key Distribution Using Entangled States
Recently, Boyer et al. presented a novel semiquantum key distribution protocol [Phys. Rev. Lett. 99 (2007) 140501] by using four quantum states, each of which is randomly prepared in the Z or X basis. Here we present a semi-quantum key distribution protocol by using maximally entangled states in which quantum …
