Based on complementary metal-oxide-semiconductor (COMS) technology—a standard low-cost, high-volume chip manufacturing technique used for most processors and chips today—a group of researchers from IBM Research in Zurich, Switzerland, together with a consortium working under the EU-funded project "ADDAPT," have demonstrated a novel optical receiver (RX) that can achieve an aggregate bandwidth of 160 Gb/s through four optical fibers.  An international team of researchers has taken an important step towards solving a difficult variation of this problem, using a statistical approach developed at the University of Freiburg.  Storing information in a quantum memory system is a difficult challenge, as the data is usually quickly lost. At TU Wien, ultra-long storage times have now been achieved using tiny diamonds.  Electronics could work faster if they could read and write data at terahertz frequency, rather than at a few gigahertz.  A team of researchers led by the Department of Energy's Oak Ridge National Laboratory has demonstrated a new method for splitting light beams into their frequency modes.  Quantum communication, which ensures absolute data security, is one of the most advanced branches of the "second quantum revolution".  Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information.  Theoretical physicists propose to use negative interference to control heat flow in quantum devices.  Particle physicists are studying ways to harness the power of the quantum realm to further their research.
