Abstract

The efficiency/security problems of the YK protocol and BB84 for data encryption can be overcome in a new technique where mesoscopic coherent states are employed to overcome loss and to allow ordinary amplification, switching and routing. A crucial new ingredient in this technique is the explicit use of a shared key for the cryptographic objective of key expansion. A free-space implementation of the new quantum technique is outlined.
