| Quantum Randomness from Untrusted Light Using a Single Photodiode | QCRYPT 2023 | Bradley Longstaff, Kieran Wilkinson, Jonatan Bohr Brask, Tobias Gehring |
Measurements in quantum physics are inherently random. Moreover, it is possible to certify quantum randomness from systems that are only partially characterized by the user. Here, we propose a simple quantum random number generator (QRNG) that requires only a single photodiode and one laser. We trust only the quantum efficiency of the photodiode and the characterization of the detector, leaving the laser in control of the eavesdropper. Such a QRNG is source-device-independent and its optical setup is among the simplest setups achieving source-device independence. |
