Quantum random-number generators (QRNGs) play a decisive role in protocols for encrypted communication. Unfortunately, classical noise often spoils both the integrity and speed of such quantum devices. The authors demonstrate a new framework to harness maximum randomness without compromising security, and which allows for more cost-effective and smaller units. This work paves the way toward a reliable, high-bit-rate, and environmentally immune QRNG for information-security applications.
