Phys. Rev. A 72, 012322 (2005) [6 pages]Decoy-state protocol for quantum cryptography with four different intensities of coherent lightSee Also: Erratum Received 2 March 2005; published 20 July 2005 We propose an efficient decoy-state protocol for practical quantum key distribution using coherent states. The protocol uses four intensities of different coherent light. A good final key rate is achieved by our protocol with typical parameters of existing practical setups, even with a very low channel transmittance. © 2005 The American Physical Society URL:
