COHERENT-STATES BASED QUANTUM DATA-ENCRYPTION THROUGH OPTICALLY-AMPLIFIED WDM COMMUNICATION NETWORKS

Title:

COHERENT-STATES BASED QUANTUM DATA-ENCRYPTION THROUGH OPTICALLY-AMPLIFIED WDM COMMUNICATION NETWORKS

Document Type and Number:

WIPO Patent Application WO2005046114

Kind Code:

A3

Abstract:

A quantum cryptographic protocol uses two-mode coherent states that is optically amplifiable, resulting in a polarization independent system that is compatible with the existing WDM infrastructure and which provides secure data encryption suitable for wavelength division multiplexing networks through an in-line amplified line.
