Need Ultrafast Information Processing? Try Topological Materials for Ultrafast Spintronics

The laws of quantum physics rule the microcosm. They determine, for example, how easily electrons move through a crystal and thus whether the material is a metal, a semiconductor or an insulator. Quantum physics may lead to exotic properties in certain materials: In so-called topological insulators, only the electrons that can occupy some specific quantum states are free to move like massless particles on the surface, while this mobility is completely absent for electrons in the bulk.

SiC! Uni Sci Tech of China Laying Foundation for Solid-State Quantum Storage and Networking

Prof. LI Chuanfeng, Prof. XU Jinshi and their colleagues from Prof. GUO Guangcan’s group, University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), realized the high-contrast readout and coherent manipulation of a single silicon carbide divacancy color center electron spin at room temperature for the first time in the world, in cooperation with Prof. Adam Gali, from the Wigner Research Centre for Physics in Hungary.
