Recently, a team of researchers at TU Delft and Element Six has successfully demonstrated a fully controllable ten-qubit spin register with a quantum memory up to one minute.  The prototype quantum memory from Faculty of Physics at University of Warsaw now takes two optical tables and functions with the help of nine lasers and three control computers.  Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor Gerhard Rempe at the Max Planck Institute of Quantum Optics (MPQ) have now achieved a major breakthrough: they demonstrated the long-lived storage of a photonic qubit on a single atom trapped in an optical resonator.  Achieving strong light-matter interaction at the quantum level has always been a central task in quantum physics since the emergence of quantum information and quantum control.  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.
