Abstract

A study is performed on secure communication using mesoscopic coherent states. A short secret key is classically extended and then used to encrypt data in a way that the quantum noise of the coherent states protects both the data and the key. It is reported that new avenues are open to secure communications at high speeds in fiber-optic or free-space channels.
