Phys. Rev. A 65, 034302 (2002) [2 pages]Addendum to “Efficient quantum-key-distribution scheme with nonmaximally entangled states”Received 21 September 2001; published 4 February 2002 The authors call attention to previous work with related result, a quantum-key-distribution scheme based on partial unknown entanglement with Wigner’s inequality to establish the security of the quantum channel. The sender chooses any entangled state from a certain set or its equivalent state randomly, and sends a sequence of particles out of each pair to the receiver. The two users each choose between two measurements along the fixed axes. In fact, this is a quantum cryptosystem based on mixed entanglement. The main paper was published in Phys. Rev.
