For decades, quantum computing has been heralded as a technology of the future, promising to solve problems far beyond the reach of supercomputers. But its practical use has remained elusive. That’s ...

Using a superconducting quantum computer, physicists created a large and complex version of an odd quantum material that has ...

Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem ...
