Quantum cooling engine fueled by quantum measurements

Caption

(a) By keeping the temperature ratio between the hot and cold baths constant, varying the energy level spacing of the working substance allows the quantum engine to operate in different thermodynamic processes. (b) The enhancement of energy extraction due to entanglement. (c)-(e) The energy exchange between the working substance and the bath under randomly chosen measurement basis.
