This live demonstration shows a monolithic quantum random number generator (QRNG) fabricated in a 22-nm standard CMOS technology and based on the dark events generated by a Single-Photon Avalanche Diode (SPAD). The random number generator relies on a novel methodology for random bit extraction based on an on-the-fly median estimation of the inter-arrival times between consecutive events. Thanks to this self-adapting mechanism, the quality of the output sequence is kept constant regardless of the working conditions.

The random number generator relies on a novel methodology for random bit extraction based on an on-the-fly median estimation of the inter-arrival times between consecutive events.
