= Josephson diode
{wiki=Josephson_diode}
A Josephson diode is a type of electronic device that exploits the Josephson effect to allow current to flow in one direction while blocking it in the opposite direction, similar to a conventional diode. The Josephson effect itself refers to the phenomenon where a supercurrent—an electrical current that flows without any resistance—passes between two superconductors separated by a thin insulating barrier (called a Josephson junction).
