We report the implementation of a quantum random number generator based on photon arrival times. Due to fast and high resolution timing we are able to generate the highest bitrate of any current generator based on photon arrival times. Bias in the raw data due to the exponential distribution of the arrival times is removed by postprocessing which is directly integrated in the field programmable logic of the timing electronics.

Further detection during the dead time does not change the length of the dead time.

Data extracted with 8 bits actually passed statistical testing and resulted in a bitrate of 76 Mbit/s.

For critical cryptographic applications the resilient function may be chosen with higher compression to limit the extracted number of bits per photon to min-entropy, 14.6 bits in our case.
