Fiber optics communication Optical security encryption
2015/6/10
Secure optical transmission experiment is demonstrated using a stream cipher by quantum noise. The bit error rates of a 10Gbit/s signal through 360km fiber for authentic receiver and eavesdropper are ...
Quantum-noise encryption using a spectral encoding protocol
Quantum-noise encryption spectral encoding protocol
2015/7/31
An innovative spectral encoding protocol is proposed, based on the coherent vector states. Irreducible quantum noise-based confidentiality is achieved with only two phase values, and sixteen frequency...
