Researchers at TU Delft have discovered a method to stretch and compress quantum materials using hydrogen gas.  Researchers from Intel Corp. and the University of California, Berkeley, are looking beyond current transistor technology and preparing the way for a new type of memory and logic circuit that could someday be in every computer on the planet.  A team of scientists from Arizona State University's School of Molecular Sciences and Germany have published in Science Advances online today an explanation of how a particular phase-change memory (PCM) material can work one thousand times faster than current flash computer memory, while being significantly more durable with respect to the number of daily read-writes.  A new two-qubit quantum processor that is fully programmable and single electron spins that can be coherently coupled to individual microwave-frequency photons are two of the latest advances in the world of solid-state spin-based quantum computing.  Scientists at the National Institute of Standards and Technology (NIST) have now developed a highly efficient converter that enlarges the diameter of a HYPERLINK "https://phys.org/tags/light/" light beam by 400 times.  There's little doubt the information technology revolution has improved our lives. But unless we find a new form of electronic technology that uses less energy, computing will become limited by an "energy crunch" within decades.  Researchers at the Niels Bohr Institute, University of Copenhagen, have recently succeeded in boosting the storage time of quantum information, using a small glass container filled with room temperature atoms, taking an important step towards a secure quantum encoded distribution network.  New work by a team at the University of Bristol's Centre for Quantum Photonics has uncovered fundamental limits on the quantum operations which can be carried out with postselection.
