AI Technical Summary
Existing quantum random number generator schemes based on laser phase noise require complex phase stabilization devices and feedback algorithms, resulting in high hardware implementation complexity and hindering practical application.
A photonic random number generator based on laser phase noise is employed. By combining a light source module, a detection module, and a data sampling and post-processing module, the laser beam is split and interfered using first and second couplers. A random number sequence is generated using a photodetector and data processing, omitting complex phase stabilization devices and feedback algorithms.
It simplifies the optical circuit structure of the system, reduces system complexity, facilitates the miniaturization and integration of the QRNG scheme, and improves the stability and robustness of the system.
