A Simple Low-latency Real-time Certifiable Quantum Random Number Generator

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate a simple scheme for generating certifiable quantum random numbers considering the imperfections in quantum devices employed. Particularly, we show low-latency real-time randomness generation from measurements on photonic time-bin states. Every 0.12s, we certify enough entropy against a quantum adversary to generate a block of 8192 random bits with a certified error bounded by 10-20. It can be run continuously and is thus well suited as a quantum randomness beacon.
