“…Overall, in the quantum systems case, it has been determined that the fluctuations theorems still remain valid provided that (i) initially the system is at thermodynamic equilibrium [28]; (ii) the system's evolution is governed by a unital quantum map, whereby the identity is a fixed point of the map [29,30]. Moreover, it is worth also mentioning results and applications [31][32][33][34] concerning the quantum Zeno effect [35], and the works by Sagawa and Ueda [36,37], together with related studies [38][39][40][41], that deal with the informational aspect of nonequilibrium thermodynamics by studying the dynamics of a quantum system subject to closed-loop control. Finally, protocols involving only series of quantum measurements or cyclical repetitions of them, have shown also the ability to fuel quantum heat engines [42,43], provided that the right measurement observable is chosen [44].…”
