Recent polarized inelastric neutron scattering experiments have identified the amplitude (i.e. Higgs) mode in C9H18N2CuBr4, a 2-D, near-quantum-critical spin ladder compound that exhibits a weak easy-axis exchange anisotropy.  On April 1 2019, the Fraunhofer-Gesellschaft launches the lighthouse project "Quantum Magnetometry" (QMag): Freiburg's Fraunhofer institutes IAF, IPM and IWM want to transfer quantum magentometry from the field of university research to industrial applications.  Majorana fermions are particle-like excitations called quasiparticles that emerge as a result of the fractionalization (splitting) of individual electrons into two halves.  With their insensitivity to decoherence, Majorana particles could become stable building blocks of quantum computers.  A team of researchers at the University of Maryland has found a new way to route photons at the micrometer scale without scattering by building a topological quantum optics interface.  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 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.
