摘要： PURPOSE: An optical phase modulation method for quantum cryptography key distribution and apparatus thereof are provided to set path difference between two paths of an asymmetric optic interferometer easily, by arranging an optic phase modulator outside the optic interferometer. CONSTITUTION: Single photon coming out from a light source(210) is inputted to an optic interferometer(220). An optic phase modulator(230) performs phase modulation to the single photon of two photos corresponding to one coordinate. The phase-modulated single photon is transmitted through an optical fiber-based quantum channel(240). An optical phase modulator(250) modulates the phase of another single photon whose phase is not modulated. Two single photos are divided in an optic interferometer(260). The overlapped photons are detected in a single photon detector(270).
