Description

technical field [0001] The invention belongs to the technical field of quantum random number generation, in particular to a quantum random number generator chip and a design method. Background technique [0002] Random numbers are a widely used basic resource, and have extensive and important applications in many fields such as quantum communication, cryptography, gaming, Monte Carlo simulation, numerical computing, random sampling, neural network computing, and traditional information security. The randomness guarantee of the quantum random number generator is derived from the principle of quantum physics. The true random number is generated by measuring the inherent random characteristics in the quantum physical system, which is unpredictable, non-repeatable and unbiased. Its randomness is determined by the quantum Compared with other random number generation technologies, what is guaranteed by the basic principles of mechanics has more advantages, so it has higher securit...
