QRANGE wants to push the QRNG (Quantum Random Number Generator) technology further, allowing for a wide range of commercial applications of QRNG. Random number generators based on quantum technologies exploit the inherent randomness of quantum physic, for a largely increased security level. The project will build three different prototypes, which are cheaper, faster and more secure than existing devices. QRANGE is funded under the EU H2020 program (H2020-FETFLAG-2018-03), grant agreement 820405.
