Scientists have built the world’s first superconducting quantum heat engine — a tiny device that converts near-absolute-zero heat into usable work, marking a leap in quantum thermodynamics and paving the way for more powerful, self-contained quantum computers. Using a transmon qubit and a clever quantum refrigerator that doubles as both hot and cold source, researchers recreated an Otto cycle at the quantum level. This innovation could eliminate the need for millions of noisy microwave cables currently required to operate large-scale quantum systems, making future quantum computers far more…
