Based on the inherent properties of quantum mechanics,quantum random numbers produce theoretically completely unpredictable true random numbers throu gh quantum physical processes,and have important applications in many fields su ch as information security,computers,and quantum communications.In order to m eet the practical application requirements of quantum random number generator,t his paper proposes a quantum random number generator design and implementation s cheme based on multiphoton state bulk noise measurement,which realizes a miniat urized,high-rate,real-time quantum random number generator,and the real-ti me output rate of quantum random number can reach 103.2 Mbps,which meets the random ness test standard of GM/T 0005-2012 Randomness Test Specification and has the ability to work continuously and stably.
