Improving these devices could mean more powerful computers, better detectors of disease and technological advances scientists can't even predict yet.  Researchers at the Schliesser Lab at the Niels Bohr Institute, University of Copenhagen, have demonstrated a new way to address a central problem in quantum physics: at the quantum scale, any measurement disturbs the measured object.  An answer to a quantum-physical question provided by the algorithm Melvin has uncovered a hidden link between quantum experiments and the mathematical field of Graph Theory.  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.  A crystalline material that changes shape in response to light could form the heart of novel light-activated devices.  Now a team of Penn State electrical engineers have a way to simultaneously control diverse optical properties of dielectric waveguides by using a two-layer coating, each layer with a near zero thickness and weight.
