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.  A collaboration between the lab of Judy Cha, the Carol and Douglas Melamed Assistant Professor of Mechanical Engineering & Materials Science, and IBM's Watson Research Center could help make a potentially revolutionary technology more viable for manufacturing.  A fundamental barrier to scaling quantum computing machines is "qubit interference." In new research published in Science Advances, engineers and physicists from Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference.  The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers.  A research team from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally occurring circular rotation.
