Quantum random number generation
Reliable and unbiased random numbers are needed for a range of applications spanning from numerical modeling to cryptographic communications. While there are algorithms that can generate pseudo random numbers, they can never be perfectly random nor indeterministic.
Researchers at the ANU are generating true random numbers from a physical quantum source. We do this by splitting a beam of light into two beams and then measuring the power in each beam. Because light is quantised, the light intensity in each beam fluctuates about the mean. Those fluctuations, due ultimately to the quantum vacuum, can be converted into a source of random numbers. Every number is randomly generated in real time and cannot be predicted beforehand. So if you need some really random numbers, visit our random number generator site.
