Researchers at Tohoku University have, for the first time, successfully demonstrated a formation and current-induced motion of synthetic antiferromagnetic magnetic skyrmions.  Researchers at the University of Colorado have recently developed a new technique to measure mechanical motion using simultaneous electromechanical amplification and cooling processes.  The global effect of quantum computing on economic and social life will depend on the use that will be made of this tool-and that stems from human decisions rather than being forced by knowledge itself.  Scientists claimed Wednesday to have achieved a near-mythical state of computing in which a new generation of machine vastly outperforms the world's fastest super-computer, known as "quantum supremacy".  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 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.
