specific Embodiment approach

[0054] A preferred embodiment of the present invention is:

[0055] The power of the LED lamp bead used is 1W, the center wavelength of the spectrum is 940nm, and the full width at half maximum is about 50nm.

[0056] Since the LED lamp bead is a thermal light source, the statistical characteristics of the light field emitted by it satisfy the thermal light field distribution and have a bunching effect, so the light intensity should be attenuated to a small enough value so that the time interval between most photons is greater than that of single photon detection The minimum resolvable time of the device. The strength of the attenuation can be judged by the counting rates of the subsequent two single-photon detectors. A more suitable degree of attenuation is that the counting rates of the single-photon detectors are several to hundreds of thousands per second. Reducing the degree of attenuation can increase the rate of random signal generation.

[0057] The detection efficien...

Abstract

The invention discloses a data post-processing type instant true random signal generator, which comprises a light source, a light beam splitter, a single-photon detector, an electric beam splitter, a pulse modulator, a random signal driving device, a data acquisition device and a data processing module, wherein a probing photon is transmitted or reflected after passing through the light beam splitter to generate a random signal; the signal is input into a device which needs random signal regulation and control after the signal is modulated; and finally, the output data of the device is subjected to post-selection processing, and an output result under true random signal regulation and control can be obtained. The data post-processing type instant true random signal generator is based on a light quantum effect, the generated random signal can pass a Rabbit standard test in TestU01, and the data post-processing type instant true random signal generator has the characteristics of low cost, high output signal timeliness and high driving performance and can be used for application fields including information encryption, quantum non-locality verification and the like.

Description

technical field [0001] The present invention relates to random signal generation technology, more specifically, to a highly time-sensitive truly random electrical signal generation device and a corresponding data post-selection method for random signal drive output. Background technique [0002] Random number generators are widely used in many modern scientific fields - such as statistical analysis, numerical simulation, algorithm design and information encryption. Random generators can be divided into three categories: pseudo-random number generators, quasi-random number generators, and true random number generators. Among them, pseudo-random numbers and quasi-random numbers are generated by various random number algorithms, the former has high statistical randomness, and the latter has high statistical uniformity. These two types of random numbers have the advantages of high generation speed without external hardware support, but because the generated random sequence is d...
