Abstract
We propose and demonstrate a scheme to realize a high-efficiency truly quantum random number generator (RNG) at room temperature. With the effective time bin encoding method, the avalanche pulses of APD is converted into intrinsically self-unbiased random number bits that is robust to slow varying noise. Light source is not necessary in this scheme. Furthermore, the experiment result indicates that a high speed RNG chip based on the scheme is potentially available with integratable APD array.
