| contents | We theoretically formulate and experimentally demonstrate a secure scheme for semi-device-independent quantum random number generation by utilizing Leggett-Garg inequality violations, within a loophole-free photonic architecture. The quantification of the generated randomness is rigorously estimated by analytical as well as numerical approaches, both of which are in perfect agreement. We securely generate $9,19,118$ truly unpredictable bits. This opens up an unexplored avenue towards an empirically convenient class of reliable random number generators harnessing the quantumness of single systems. |
