A new technique developed by a team at MIT can map the complete electronic band structure of materials at high resolution.  Correlations between the radial positions and radial momenta of entangled pairs of photons have been measured for the first time by physicists in China, Canada and the US.  Researchers led by Tracy Northup at the University of Innsbruck have now built a quantum sensor that can measure light A team of researchers with members from IBM Research-Zurich and RWTH Aachen University has announced the development of a new PCM (phase change memory) design that offers miniaturized memory cell volume down to three nanometers.  Monatomic glassy antimony might be used as a new type of single-element phase change memory.  Physicists have designed a 3-D quantum memory that addresses the tradeoff between achieving long storage times and fast readout times, while at the same time maintaining a compact form.  Quantum memories are devices that can store quantum information for a later time, which are usually implemented by storing and re-emitting photons with certain quantum states.
