A photon detection device having a high light detection efficiency. The photon detection device includes a first light reception part which receives a gate signal and outputs a first signal; a second light reception part which receives a gate signal and outputs a second signal; and a determination part which determines whether or not a photon is received, on the basis of the first signal from the first light reception part and the second signal from the second light reception part. The photon is incident on the first light reception part among the first light reception part and the second light reception part, and the breakdown voltage of the second light reception part is higher than the breakdown voltage of the first light reception part.

Detection of photon by pairing avalanche photodiodes with different threshold voltages

The present disclosure discloses a random number generating apparatus capable of equalizing the spatial intensity distribution of light signals that are radiated from a light resource and are input to individual pixels.

Quantum noise-based random number generating apparatus utilizing a plurality of light sources

The present invention presents a device and method for managing the performance of a quantum noise-based random number generator, the device ensuring the performance stability of a random number generator on the basis of an output value for each pixel, which is outputted in correspondence to an optical strength value of an optical signal emitted from a light source and inputted into each pixel, so as to be capable of outputting, within a certain range regardless of devices, a value of an entropic signal outputted from an image sensor, thereby enabling sufficient randomness to be continuously maintained while minimizing deviation between pixels.
