More Randomness

True Random Number Generator Goes Online (07/18/07) Panditaratne, Vidura

Academics and members of the scientific community will not be able to accurately predict the next number that comes out of the Quantum Random Bit Generator Service (QRBGS). The QRBGS is unlike the random number generators of most computers, which employ different algorithms to choose a number from large databases that use methods such as rolling the dice to compile their numbers. Such random number generators deliver essentially pseudo-random numbers, but QRBGS uses photon emission, the unpredictable quantum process, to produce true random numbers. QRBGS makes use of a fast non-deterministic random bit generator, and its random quality comes from the quantum physical process of photonic emission in semiconductors, followed by detection from the photoelectric effect. Developed by computer scientists at the Ruder Boskovic Institute (RBI) in Zagreb, Croatia, QRBGS has been made available online, connected by computer clusters and GRID networks, free of charge. Potential applications include advanced scientific simulations, cryptographic data protection, security applications, and virtual entertainment.
