Research output: Working paperPreprint


Self-testing and Semi-Device Independent protocols are becoming the preferred choice for quantum technologies, being able to certify their quantum nature with few assumptions and simple experimental implementations. In particular for Quantum Random Number Generators the possibility of monitoring in real time the entropy of the source only by measuring the input/output statistics is a characteristic that no other classical system could provide. The cost of this new possibility is not necessarily increased complexity and reduced performance. Indeed, here we show that with a simple optical setup consisting of commercially available components, a high bit generation rate can be achieved. We manage to certify 145.5~MHz of quantum random bit generation rate.
