Quantum computers could someday solve pressing problems that are too convoluted for classical computers, such as modeling ...

Separate two superconductors with a thin layer of material and something strange happens. Their superconductivity — a property driven by paired electrons that allows electricity to flow without energy ...

Josephson junctions are quantum mechanical devices consisting of two superconductors separated by a thin insulating barrier. They are named after Brian Josephson, who predicted their unique properties ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in ...

A Superconducting Quantum Interference Device (SQUID) is an ultrasensitive superconducting sensor used to measure extremely small changes in magnetic flux. It consists of a superconducting loop ...

An image of a superconducting quantum computer shows several round, flat, golden layers with tubes and wires between them, all encased in a transparent cylinder. The superconducting quantum computer ...
