I started thinking about it, and eureka\u2014since quantum measurements are very invasive, they are accompanied by energy exchanges, hence can be used to power engines without the need to do feedback control.\u201d<\/p>\n<p><!-- Link: <a href=\"https:\/\/phys.org\/news\/2019-03-quantum-fuel-cooling.html\">https:\/\/phys.org\/news\/2019&#45;03-quantum-fuel-cooling.html<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at the University of Florence and Istituto dei Sistemi Complessi, in Italy, have recently proved that the invasiveness of quantum measurements might not always be detrimental.
