Title:
HIGH-SPEED QUANTUM RANDOM NUMBER GENERATOR BASED ON VACUUM STATE FLUCTUATION TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2021/244491
Kind Code:
A1
Abstract:
A high-speed quantum random number generator based on a vacuum state fluctuation technology, comprising a laser light source (1), an unequal proportion optical splitter (2), a programmable logic device (3), n groups of differential detectors (4), and n groups of amplifiers (5) and analog-to-digital converters (6) connected sequentially. A laser signal emitted by the laser light source (1) is divided into n paths of first light beams and n paths of second light beams by the unequal proportion optical splitter (2), wherein each path of the first light beam corresponds to one path of the second light beam and is inputted into input ends of one group of the differential detectors (4), output ends of each group of the differential detectors (4) are correspondingly connected to an input end of one amplifier (5), and output ends of the analog-to-digital converters (6) are connected to an input end of the programmable logic device (3).
