In this brief, we present a 16 × 16-pixel quantum random number generator (QRNG) based on Single-Photon Avalanche Diodes, implemented in CMOS 150-nm technology. Each pixel consists of two detectors, featuring 17.2 μm ×7.7 μm size, and an arbiter, based on a phase comparator, enhancing the working range of the generator. The QRNG has achieved a random bit efficiency of 90% at a given observation window of 200 ns. The maximum speed is up to 18.2 Mbps for the whole array due to limited readout capability. The measurement result shows the random numbers can pass the standard randomness test without any post-processing.

Abstract

In this brief, we present a 16 × 16-pixel quantum random number generator (QRNG) based on Single-Photon Avalanche Diodes, implemented in CMOS 150-nm technology. Each pixel consists of two detectors, featuring 17.2 μm ×7.7 μm size, and an arbiter, based on a phase comparator, enhancing the working range of the generator. The QRNG has achieved a random bit efficiency of 90% at a given observation window of 200 ns. The maximum speed is up to 18.2 Mbps for the whole array due to limited readout capability. The measurement result shows the random numbers can pass the standard randomness test without any post-processing.
