Quantum Random Number Generation on a Mobile Phone

Quantum Random Number Generation on a Mobile Phone

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...
