Maximization of Extractable Randomness in a Quantum Random-Number Generator

摘要: The generation of random numbers via quantum processes is an efficient and reliable method to obtain true indeterministic that are vital importance cryptographic communication large-scale computer modeling. However, in realistic scenarios, the raw output a random-number generator inevitably tainted by classical technical noise. integrity device can be compromised if this noise tampered with, or even controlled some malicious party. To safeguard against this, we propose experimentally demonstrate approach produces side-information independent randomness quantified min-entropy conditioned on We present for maximizing conditional number sequence generated from given quantum-to-classical-noise ratio. detected photocurrent our experiment shown have real-time rate 14 (Mbit/s)/MHz. spectral response detection system shows potential deliver more than 70 Gbit/s experimental setup.
