Assignee: TRUSTEES OF DARTMOUTH COLLEGE
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A quantum random number generator (QRNG), comprising:
a Quanta Image Sensor (QIS) comprising a pixel array, wherein each pixel of the QIS is configured to convert photons emitted from a photon source into photocarriers having electrical charge, wherein the QIS is configured to readout each pixel to provide a signal representing a number of the photocarriers collected within a time interval with single-photocarrier sensitivity; and
wherein the QRNG is configured to output random number data having randomness based on the number of collected photocarriers within the time interval, wherein for each pixel the number of photocarriers collected within the time interval is converted to a voltage and then into a binary signal using a threshold level that can be adjusted by adjusting a reference voltage.
