Straight Motion of Magnetic Skyrmions

Authors: George Rajna

Researchers at Tohoku University have, for the first time, successfully demonstrated a formation and current-induced motion of synthetic antiferromagnetic magnetic skyrmions. [35] Researchers at the University of Colorado have recently developed a new technique to measure mechanical motion using simultaneous electromechanical amplification and cooling processes. [34] 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. [33] 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". [32] Quantum communication, which ensures absolute data security, is one of the most advanced branches of the "second quantum revolution". [31] 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. [30] Theoretical physicists propose to use negative interference to control heat flow in quantum devices. [29] Particle physicists are studying ways to harness the power of the quantum realm to further their research. [28] 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.
