AI Article Synopsis
- The text describes a quantum random number generator (QRNG) that uses single photon detection in light to produce random numbers.
- It highlights how the device cleverly uses deadtime effects from photomultiplier tubes to eliminate the need for extra processing to correct biases or correlations in the output.
- With a high generation rate of up to 50 Mbit/s, the QRNG produces numbers that successfully meet all standards for physical randomness.
Article Abstract
We present a fully integrated, ready-for-use quantum random number generator (QRNG) whose stochastic model is based on the randomness of detecting single photons in attenuated light. We show that often annoying deadtime effects associated with photomultiplier tubes (PMT) can be utilized to avoid postprocessing for bias or correlations. The random numbers directly delivered to a PC, generated at a rate of up to 50 Mbit/s, clearly pass all tests relevant for (physical) random number generators.
