An approach to quantum random number generation based on unambiguous quantumstate discrimination (USD) is developed. We consider a prepare-and-measureprotocol, where two non-orthogonal quantum states can be prepared, and ameasurement device aims at unambiguously discriminating between them. Becausethe states are non-orthogonal, this necessarily leads to a minimal rate ofinconclusive events whose occurrence must be genuinely random and which providethe randomness source that we exploit. Our protocol is semi-device-independentin the sense that the output entropy can be lower bounded based on experimentaldata and few general assumptions about the setup alone. It is also practicallyrelevant, which we demonstrate by realising a simple optical implementationachieving rates of 16.5 Mbits/s. Combining ease of implementation, high rate,and real-time entropy estimation, our protocol represents a promising approachintermediate between fully device-independent protocols and commercial QRNGs.
