If you've ever needed true random numbers and not known where to get them, there's now a web site where you can download some. The underlying technology was developed by the Group of Applied Physics of the University of Geneva in 1998. The device exploits an elementary quantum optical process - namely the reflection or the transmission of a light particle on a semi-transparent mirror - to produce binary random numbers. The quantum random number generator technology was commercialized by id Quantique, a spin-off of the University of Geneva. As far as I can tell, there's no Web services interface. In fact, they seem to be going down the road of creating individual programming language SDKs. That's a mistake as far as I can see.
