The generation of random numbers is an essential building block for encrypted communication and equally indispensable for numerical simulations. In the course of the great development of quantum technologies, more and more so-called quantum random number generators (QRNGs) are emerging. Quantum physics offers true randomness, which is used for the development of QRNGs.
On this topic Dr. Markus Gräfe together with Dr. Manfred Lochter from the Federal Office for Information Security (BSI) organized the workshop "Quantum Random Number Generation" at Fraunhofer IOF from January 23rd-24th, 2020.
During the two days, the approximately 30 participants explored, among other things, the question of what actually constitutes a quantum random number generator, what types of random number generators have been available to date and how they differ from physical random number generators, or what their advantages and disadvantages are.

In order to stimulate the scientific exchange between the quantum physicists, cryptographers and industry representatives present, there was sufficient opportunity for detailed discussions in addition to lectures.
Markus Gräfe summarized the workshop: "It was an all-round successful event that brought all parties further together. Everyone leaves the workshop with new insights".
