Abstract

Functional diagram of unique key quantum distribution system on chopped light sideband with unconditional
security is suggested. Sidebands application allows simplifying optical phase insertion into operational signals. Compensation mechanisms of optical modulator polarization dependence and negative influence of
birefringence are discussed and proved by experimental results.


Keywords: quantum cryptography, secure key distribution, sidebands
