An international research team has developed a fast and affordable quantum random number generator.

The device created by scientists from NUST MISIS, Russian Quantum Center, University of Oxford, Goldsmiths, University of London and Freie Universität Berlin produces randomness at a rate of 8.05 gigabits per second, which makes it the fastest random number generator of its kind.

Random number generators implemented in software based algorithms produce random-looking yet deterministic sequences of numbers, which poses numerous information security vulnerabilities.

Since randomness is a fundamental property of quantum processes, quantum events can be harnessed to generate truly random numbers.

"Quantum events allow the generation of numbers whose randomness is asserted based upon the underlying physical processes. Quantum-based random number generators can have very broad applications," noted Alex Fedorov, head of the Russian Quantum Center research group and the Quantum Communications Theory Lab Head at NUST MISIS. In their experiments, the researchers sent light from the "Untrusted" light source into one input of a beam splitter while the other input was the vacuum.

The new RNG generates random numbers at a rate of 8.05 gigabits per second - which makes it the fastest composably secure quantum random number generator ever reported- and provides real-time randomness certification.
