Abstract: Semi-quantum cryptography involves at least one party who is semi-quantum or “classical” in nature. Such a party can only interact with the quantum channel in a very limited way. Many semi-quantum key distribution protocols have been developed, some with rigorous proofs of security. In our work we show for the first time that quantum random number generation is possible in the semi-quantum setting. We develop a rigorous proof of security, deriving a bound on the random bit generation rate of the protocol as a function of noise in the channel. Our protocol and proof may be broadly applicable to other quantum and semi-quantum cryptographic scenarios where parties are limited in their capabilities.
