Inferring work by quantum superposing forward and time-reversal evolutions

Quantum thermodynamics under continuous monitoring: a general framework

“…On the more practical side, although the TPM have been directly implemented in several experiments [197][198][199][200][201] , projective measurements are often difficult to control and may destroy the quantum system over which they are performed. Alternative schemes reproducing their results have been hence proposed which reproduce the TPM statistics by using indirect measurements and interferometry techniques 114,[202][203][204][205][206][207] . Some of these alternative scheme have been successfully tested in the laboratory to measure work distributions and test fluctuation theorems in closed systems [208][209][210] .…”

Thermodynamics of quantum switch information capacity activation

“…The setting wherein information capacity is increased via the quantum switch was shown to give an apparent violation of the dataprocessing inequality [9], which is closely connected to the second law [21], as well as enable the separation between hot and cold [22][23][24]. A more general study of superpositions of thermodynamic processes is beginning [25][26][27]. These intriguing results raise the question of whether the laws of thermodynamics and the information capacity increase of the switch are compatible, and if so how.…”

“…It is very intriguing that only a limited activation capacity from the switch is allowed for thermal state preserving channels, and one wonders whether there is a simple reason for this. A connected question is the important question of what the difference is between the switch and other coherent combinations of channels [25][26][27][37][38][39][40][41][42].…”
