摘要：
A quantum key distribution protocol using an optical states based on nonorthogonal entangled pairs is investigated. It consists of sharing a similar key between the sender and the receiver by exchanging the quantum correlation of coherent states. These states are used as the support of the encoding information where affected by an amplitude damping channel. The security of the present protocol against beam splitter attack is studied as function of the information gain.
