  • A superconducting layer placed between two ferromagnetic insulators can drive an antiferromagnetic exchange coupling between them. Here, the authors demonstrate that such an exchange coupling promotes non-volatile bistable memory states and repeatable “absolute” switching in GdN/V/GdN, where the device exhibits a superconducting transition only when the two ferromagnets have anti-parallel magnetization.

  • The ability to coherently manipulate single electrons and photons is vital for quantum information processing. Experiments now demonstrate optical initialization, manipulation and probing of a single quantum dot on femtosecond timescales, revealing signatures of interaction effects, optical gain and the ability to change the number of quanta in a light pulse by one.
