Physicists have also devised photonic topological insulators, synthetic materials that impart light waves with distinct topological features, allowing light (rather than electric currents) to flow via topological surface states.  "This research highlights the cutting-edge research being done at WVU, and we are very excited to see their work appear in the very high-profile journal Nature Communications."  By constructing a hybrid device made from two different types of qubit—the fundamental computing element of quantum computers—they have created a device that can be quickly initialized and read out, and that simultaneously maintains high control fidelity.  Researchers have demonstrated that an amoeba—a single-celled organism consisting mostly of gelatinous protoplasm—has unique computing abilities that may one day offer a competitive alternative to the methods used by conventional computers.  For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew.  Physical systems with discrete energy levels are ubiquitous in nature and form fundamental building blocks of quantum technology.
