It is really hard to follow context of article, guess is not written for us mortals. My primitive understanding that is most likely wrong; > If it sounds implausible, it is: After much thrill and controversy, a 2014 proof showed that Wilczek’s prescription fails, like all other perpetual-motion machines conceived throughout history. > Furthermore, the spins never absorbed or dissipated net energy from the microwave laser, leaving the disorder of the system unchanged. Seems like maintaining stable quantum state A or B costs energy, but changing quantum state from A to B or from B to A does not somehow introduces additional order/disorder to a quantum system and changing state costs energy. (this still confuses me, obviously)
