Scientists just captured a mysterious quantum “dance” inside superconductors

Scientists just spotted a mysterious quantum “dance” that could rewrite superconductivity—and reshape future tech. For the first time, researchers have directly visualized the quantum behavior that drives superconductivity, a state in which paired electrons allow electricity to flow with zero resistance at very low temperatures.

But what they observed came as a surprise.

In a study published April 15 in Physical Review Letters, the team captured images of individual atoms forming pairs inside a specially prepared gas cooled to nearly absolute zero — the unreachable limit to how cold anything can get...
