Such an inequality, which we call the “thermodynamic reverse bound,” is compactly expressed as a quantum relative entropy, from which it inherits mathematical properties and meaning. As concrete examples, we apply our bound to evaluate the thermodynamic length for open processes, the heat exchange in erasure processes, and the maximal energy outflow in general quantum evolutions.American Physical Society2021-09-102020-09engjournal articleVoRhttp://hdl.handle.net/2237/0002001429https://nagoya.repo.nii.ac.jp/records/2001429https://doi.org/10.1103/PhysRevA.102.0322102469-9926Physical Review A1023032210https://nagoya.repo.nii.ac.jp/record/2001429/files/PhysRevA_102_032210.pdfapplication/pdf318 KB2021-09-10
