@PRL Quantum engine operating at maximum power
A new experimental proof-of-concept quantum Otto cycle, using nuclear spins, has reached an efficiency close to its thermodynamic limit at maximum power.
The so-called quantum technology relies on microscopic devices that obey the laws of quantum mechanics. But how much power will this new type of devices need in practice? How much heat will be produced? How to operate in the optimal condition dissipating minimum energy? These questions have just starting to be answered thr
