The field of topological photonics, specialized in the development of a class of materials known as photonic topological insulators, has advanced considerably over the past few decades. Photonic topological insulators have ...
(PhysOrg.com) -- Exerting delicate control over a pair of atoms within a mere seven-millionths-of-a-second window of opportunity, physicists at the University of Wisconsin-Madison created an atomic circuit that may help quantum ...
