Abstract

Lasers are recently being used more frequently in random number generators. The world record in random number generation was broken by the help of lasers. The world's fastest quantum random number generators utilize lasers to tap into the random fluctuations in order to extract true random bit sequences. We investigate a system based on a Nd:YAG laser that potentially generates true random bits at Gbit/s rates. As photonic on chip technologies progress we foresee laser based high speed random number generators integrated on chips. Such a photonic chip will create a revolution in the technology of security devices that employ quantum cryptography techniques for secure communication.
