Quantum-noise protected data encryption for WDM networks

We demonstrate quantum-noise protected data encryption over a 2OOkm optically amplified WDM fiber line at 650Mbps rate using off-the-shelf components. This demonstration paves the way for widespread deployment of quantum cryptography in WDM networks.
