Method and apparatus for highly effective on- chip quantum random number generator
A true random number generator is presented that includes a CMOS matrix detector with a top surface. A shell is positioned over the top surface, and the shell includes a radiation source and a luminophore or scintillator constructed to emit photons towards the top surface when the luminophore or scintillator is struck by electrons from the radioactive decay of the source of the radiation. The CMOS detector matrix is constructed to detect the photons emitted from the luminophore or scintillator and to produce a signal for the detected photons. The signal is communicated to a processor that produces true random numbers based on the signal from the detected photons.
