Quantum mechanics enables the operational generation and certification of genuine, unpredictable random numbers based solely on observed experimental statistics. Besides being a fundamental signature of nonclassical physical processes, intrinsically random numbers form a valuable resource for crucial applications such as device-independent cryptography, unbiased poling, gambling, and efficient numerical simulation of physical and biological systems. Even though several device-independent and semi-device-independent randomness certification schemes have been introduced, and their proofs-of-concept have been experimentally demonstrated, they remain impractical due to their low noise tolerance and highly stringent requirements on the quality of the equipment. In particular, the exceptionally high critical detection efficiency requirement and low noise tolerance of the device-independent randomness certification schemes, which rely on violation of Bell inequalities, render them infeasible for near-term practical applications. This project aims to remedy this situation and develop, analyze, and implement device-independent and semi-device independent protocols for generation, certification, and expansion of random numbers that can tolerate high levels of noise and detector inefficiency and require minimal equipment characterization.
