Type: article
Abstract: Generating certifiably random bit sequences using quantum devices is a fundamental challenge for cryptography, particularly as applied to secure communication. The device-independent approach offers the best security, but is impractical. This study presents a quantum random-number generator (QRNG) that is simple and achieves high bit rates, yet requires only mild assumptions (almost no trust) regarding the setup. This protocol offers a promising solution for the next generation of QRNGs, combining ease of implementation, commercially viable rates, and strong security.
