Using a high-speed serial data transceiver (1130) to generate two paths of high-speed electric pulse signals (P1, P2). After the signals pass through a gain-control network (1200), the signals are used for driving an electro-optic phase modulator (PM) to realize the phase modulation of light quantum signals. Without the use of a D/A converter or an analogue switch, a high-speed digital signal is directly used to realize a four-phase modulating function required by a BB84 quantum key distribution protocol. Therefore, the limitation to a modulating speed caused by digital-to-analogue conversion, analogue switch switching and the like can be avoided. A dual-pole electro-optic phase modulator scheme also can effectively reduce the range requirements of modulation driving signals, and is good for realizing high-speed phase modulation meeting the requirements of quantum key distribution.
