Simple delay scheme for quantum cryptography based on a Mach-Zehnder optic fiber interferometer
S. N. Molotkov · Journal of Experimental and Theoretical Physics Letters · 2003
A simple experimental scheme is proposed for a relativistic quantum cryptosystem based on a Mach-Zehnder optic fiber interferometer. In this scheme, quantum mechanical laws, along with the restrictions imposed by the Special Relativity, ensure the detection of any eavesdropping attempt.
