Quantum Random Number Generation on a Mobile Phone

Year: 2014

Type: article

Abstract: Quantum random number generators (QRNGs) can significantly improve the security of cryptographic protocols by ensuring that generated keys cannot be predicted.However, the cost, size, and power requirements of current Quantum random number generators have prevented them from becoming widespread.In the meantime, the quality of the cameras integrated in mobile telephones has improved significantly so that now they are sensitive to light at the few-photon level.We demonstrate how these can be used to generate random numbers of a quantum origin.
