Superfast data processing using light pulses instead of electricity has been created by scientists.  Yao-Lung (Leo) Fang, an assistant computational scientist with the Quantum Computing Group in Brookhaven's Computational Science Initiative and a co-author of the paper, explained that a particle occupying a stable bound state is confined in space, such as an electron orbiting a hydrogen atom.  MIT researchers have designed a way to generate, at room temperature, more single photons for carrying quantum information. The design, they say, holds promise for the development of practical quantum computers.  Operation at the single-photon level raises the possibility of developing entirely new communication and computing devices, ranging from hardware random number generators to quantum computers.  Considerable interest in new single-photon detector technologies has been scaling in this past decade.  Engineers develop key mathematical formula for driving quantum experiments.  Physicists are developing quantum simulators, to help solve problems that are beyond the reach of conventional computers.  Engineers at Australia's University of New South Wales have invented a radical new architecture for quantum computing, based on novel 'flip-flop qubits', that promises to make the large-scale manufacture of quantum chips dramatically cheaper-and easier-than thought possible.  A team of researchers from the U.S. and Italy has built a quantum memory device that is approximately 1000 times smaller than similar devices-small enough to install on a chip.  The cutting edge of data storage research is working at the level of individual atoms and molecules, representing the ultimate limit of technological miniaturisation.  This is an important clue for our theoretical understanding of optically controlled magnetic data storage media.
