A new approach to trapping light in artificial photonic materials by a City College of New York-led team could lead to a tremendous boost in the transfer speed of data online.  The first system for reshaping the time-varying profiles of individual photons has been created by Olivier Morin and colleagues at the Max-Planck-Institute for Quantum Optics in Garching, Germany.  Recently, the chemists Sebastian Mai and Leticia González from the Faculty of Chemistry of the University of Vienna succeeded in simulating the extremely fast spin flip processes that are triggered by the light absorption of metal complexes.  University of Tokyo researchers have announced a new approach for electrical cooling without the need for moving parts.  When electrons that repel each other are confined to a small space, they can form an ordered crystalline state known as a Wigner crystal.  A new experiment that tests the limit of how large an object can be before it ceases to behave quantum mechanically has been proposed by physicists in the UK and India.  Phonons are discrete units of vibrational energy predicted by quantum mechanics that correspond to collective oscillations of atoms inside a molecule or a crystal.  This achievement is considered as an important landmark for the realization of practical application of photon upconversion technology.  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.
