Quantum-limited heat conduction over macroscopic distances - Aalto University

At ultimately thin heat conduction channels, the power flowing between two bodies is fundamentally limited. This power is given by the quantum of thermal conductance. Now this kind of quantum-limited heat conduction has been experimentally demonstrated in Quantum Computing and Devices Laboratories (QCD Labs) headed by Prof. Mikko Möttönen. Their work published in Nature Physics, the team extends the range of quantum-limited heat conduction by a factor of 10,000 using microwave photons in the framework of ci
