Analog of differential–phase quantum cryptography on coherent states with provable cryptographic security
S. N. Molotkov · Journal of Experimental and Theoretical Physics Letters · 2015
A quantum-cryptography protocol has been proposed by analogy with distributed coding protocols operating at sub- and gigahertz clock frequencies. In contrast to distributed coding protocols whose security has not yet been proved, this protocol allows a simple, intuitively clear proof of security.
