In order to reduce error rates even further and provide reliable operations much faster, researchers at Leibniz University Hannover and Physikalisch-Technische Bundesanstalt (PTB) have now developed a new method.  Scientists with the Institute for Molecular Engineering at the University of Chicago have made two breakthroughs in the quest to develop quantum technology.  A theoretical concept to realize quantum information processing has been developed by Professor Guido Burkard and his team of physicists at the University of Konstanz.  As the number of hacks and security breaches rapidly climbs, scientists say there may be a way to make a truly unhackable network by using the laws of quantum physics.  This world-first nanophotonic device, just unveiled in Nature Communications, encodes more data and processes it much faster than conventional fiber optics by using a special form of 'twisted' light.  Purdue University researchers created a new technique that would increase the secret bit rate 100-fold, to over 35 million photons per second.  Physicists at The City College of New York have used atomically thin two-dimensional materials to realize an array of quantum emitters operating at room temperature that can be integrated into next generation quantum communication systems.  Research in the quantum optics lab of Prof. Barak Dayan in the Weizmann Institute of Science may be bringing the development of such computers one step closer by providing the "quantum gates" that are required for communication within and between such quantum computers.  Calculations of a quantum system's behavior can spiral out of control when they involve more than a handful of particles.
