Recent developments in the realization of quantum computers offer new opportunities in many fields of research but at the same time put current cryptographic systems at risk.Quantum technology, however, offers great opportunities to evolve cryptographic systems to new levels of security through the use of quantum random number generators (QRNGs) and quantum key distribution systems (QKDs). In this presentation I will explain the basics of QRNG and QKD systems and I will give some examples of the use of these technologies within IT datacenters.
