quRNG

Postprocessing-free high speed (50 Mbit/s) random bit generator based on quantum mechanics.

qutools’ quRNG 50 is a quantum random number generator (QRNG, also known as quantum random bit generator QRBG) producing true random numbers with a maximum bit rate of 50 Mbit/s. It is read out via a USB-2.0 interface.

The source of randomness is based on the uncertainty of the detection time of photons emitted from a light emitting diode (LED). These photons are collected by a single photon detector at a high rate and subsequently digitized. The random bit stream can be output at an adjustable rate. With careful tuning of the LED’s light intensity, post processing can be omitted completely.

The output of the quRNG 50 passes the usual test suites for physical random number generators (see test report).

There is a research and an industrial version available. Both versions continuously run tests on the state of the random bit stream to ensure their high quality level.
