Abstract

We demonstrate quantum-noise protected data encryption over a 200km-long inline optically-amplified fiber line at 650Mbps rate using off-the-shelf components. In contrast to our previous implementation, this demonstration uses phase-encoded coherent states, resulting in a polarization independent system that is compatible with the existing WDM infrastructure. Security calculations are presented for individual attacks on both the encrypted data as well as the secret key. This demonstration paves the way for widespread deployment of quantum cryptography in WDM networks.
