Compact Quantum Random Number Generator Based On Superluminescent Light-Emitting Diodes
REVIEW OF SCIENTIFIC INSTRUMENTS(2017)
Abstract
By measuring the amplified spontaneous emission (ASE) noise of the superluminescent light emitting diodes, we propose and realize a quantum random number generator (QRNG) featured with practicability. In the QRNG, after the detection and amplification of the ASE noise, the data acquisition and randomness extraction which is integrated in a field programmable gate array (FPGA) are both implemented in real-time, and the final random bit sequences are delivered to a host computer with a real-time generation rate of 1.2 Gbps. Further, to achieve compactness, all the components of the QRNG are integrated on three independent printed circuit boards with a compact design, and the QRNG is packed in a small enclosure sized 140 mm x 120 mm x 25 mm. The final random bit sequences can pass all the NIST-STS and DIEHARD tests. (c) 2017 Author(s).
