HP Labs' Quantum Information Processing Group has made a discovery which permits bits of light in a quantum computing environment to interact with each other. This method also surmounts a previous hurdle where information carrying photons were destroyed upon detection by the act of imprinting themselves on photon light detectors. The emergence of working quantum processors is expected to herald a new age for information technology, replacing binary bit values with an infinite choice of numerical allocations.
