“…Based on Born's postulate, several quantum random number generators employing beam splitters have recently been proposed and realized [8][9][10][11][12][13][14][15]. In what follows a detailed analysis of bit strings of length 2 32 obtained by two such quantum random number generators will be presented.…”

“…QRNGs based on entangled photon pairs have been realized by a second Chinese group in Beijing and Ji'nan [18], who utilized spontaneous parametric down-conversion to produce entangled pairs of photons. One of the photons has been used as trigger, mostly to allow a faster data production rate by eliminating double counts.…”

In this paper we propose a quantum random number generator (QRNG) which utilizes an entangled photon pair in a Bell singlet state, and is certified explicitly by value indefiniteness. While "true randomness" is a mathematical impossibility, the certification by value indefiniteness ensures the quantum random bits are incomputable in the strongest sense. This is the first QRNG setup in which a physical principle (Kochen-Specker value indefiniteness) guarantees that no single quantum bit produced can be classically computed (reproduced and validated), the mathematical form of bitwise physical unpredictability.The effects of various experimental imperfections are discussed in detail, particularly those related to detector efficiencies, context alignment and temporal correlations between bits. The analysis is to a large extent relevant for the construction of any QRNG based on beam-splitters. By measuring the two entangled photons in maximally misaligned contexts and utilizing the fact that two rather than one bitstring are obtained, more efficient and robust unbiasing techniques can be applied. A robust and efficient procedure based on XORing the bitstrings together-essentially using one as a one-time-pad for the other-is proposed to extract random bits in the presence of experimental imperfections, as well as a more efficient modification of the von Neumann procedure for the same task. Some open problems are also discussed.

“…The randomness in path taken by photons arriving on a beam splitter 1 [1], the comparison of the waiting time for photon arrivals in adjacent time intervals [2] and the combination of both methods [3] have been used to generate random numbers. In some other works, encoding the number of arriving photons in observation windows [4][5][6] and the randomness in the photon arrival times [7][8][9] have been used to produce random numbers.…”

“…Recently, a robust approach based on arrival times of photons has been proposed by our group [9]. It considers all the non-idealities of the source as well as the detector, producing high quality random numbers which pass all the statistical tests in national institute of standards and technology (NIST) tests suite and TestU01 without a post-processing algorithm 1 .…”

A small-sized photonic quantum random number generator, easy to be implemented in small electronic devices for secure data encryption and other applications, is highly demanding nowadays. Here, we propose a compact configuration with Silicon nanocrystals large area light emitting device (LED) coupled to a Silicon photomultiplier to generate random numbers. The random number generation methodology is based on the photon arrival time and is robust against the non-idealities of the detector and the source of quantum entropy. The raw data show high quality of randomness and pass all the statistical tests in national institute of standards and technology tests (NIST) suite without a post-processing algorithm. The highest bit rate is 0.5 Mbps with the efficiency of 4 bits per detected photon.
