Practical Source‐ Device‐Independent Quantum random number generators
14:45 - 15:05
Marco Avesani, Davide G. Marangon, Hamid Tebyanian, Giuseppe Vallone and Paolo Villoresi Randomness is an invaluable resource for many applications. Quantum random number generators (QRNG) offer an advantage over other solutions because they exploit the intrinsic randomness of quantum mechanics to generate secure random numbers. However, practical QRNG usually require to trust the inner working of their components and their security can be completely compromised in case of malfunction or malicious external actions. Here we describe a series of works where the source is untrusted and the security is evaluated in the Source-Device-Independent scenario. We experimentally realized the protocols with photonic implementations, reaching secure rates that match the requirements of practical applications.
