ANU Quantum Random Number ServerThis website offers true random numbers to anyone on the internet. The random numbers are generated in real-time in our lab by measuring the quantum fluctuations of the vacuum. The vacuum is described very differently in the quantum mechanical context than in the classical context. Traditionally, a vacuum is considered as a space that is empty of matter or photons. Quantum mechanically, however, that same space resembles a sea of virtual particles appearing and disappearing all the time. This results in the fact that the vacuum does not possess a zero-point energy, and consequently the electo-magnetic field describing this vacuum possesses random fluctuations in phase and amplitude at all frequencies. By carefully measuring these fluctuations, we are able to generate ultra-high bandwidth random numbers.
The hardware is constantly generating random bits at a rate of 5.7Gbits/s. Currently, the rate at which the live bits are streamed is being limited by the bandwidth of the internet connection.
