Abstract

We propose and demonstrate a scheme to realize a high-efficiency truly quantum random number generator (RNG) at room temperature. Using an effective extractor with simple time bin encoding method, the avalanche pulses of avalanche photodiode (APD) are converted into high-quality random numbers that are robust to slow varying noise such as fluctuations of pulse intensity and temperature. A light source is compatible but not necessary in this scheme. Therefor the robustness of the system is effective enhanced. The random bits generation rate of this proof-of-principle system is 0.69 Mb/s with double APDs and 0.34 Mb/s with single APD. The results indicate that a high-speed RNG chip based on the scheme is potentially available with an integrable APD array.
