Physicists Developed a Superconductor Circuit Long Thought to Be Impossible
By exchanging a classical material for one with unique quantum properties, scientists have made a superconducting circuit that's capable of feats long thought to be impossible. The discovery, made by researchers from Germany, the Netherlands, and the US, overturns a century of thought on the nature of superconducting circuits, and how their currents can be tamed and put to practical use.
