... probability of occurring is constant, then, given n bins, log 2 n random bits will be generated per detection event [3]. Discrete random variables give output probabilities that take the form of a decaying exponential (instead of the uniform distribution which is defined as a probability density function for only continuous random variables). Fig. 2 shows the waiting time distribution for the random arrival times of photons [11]. ...

... contained in a message, and is referred to as the entropy. When used in this context, the term entropy typically refers to Shannon entropy. There are, however, related measures of entropy that are of special interest in RNGs. QRNGs based on photon arrival times have an output waiting-time distribution of the form of − e Rt , as shown in Fig. 2, where R is the photon rate of single-photon detector and t is the time until the next photon is detected ...

... it becomes increasingly important to properly quantify the amount of randomness that is generated. In information theory, this is also analogous to the amount of information contained in a message, and is referred to as the entropy. When used in this context, the term entropy typically refers to Shannon entropy. There are, however, related measures of entropy that are of special interest in RNGs. QRNGs based on photon arrival times have an output waiting-time distribution of the form of − e Rt , as shown in Fig. 2, where R is the photon rate of single-photon detector and t is the time until the next photon is detected ...
