The role of quantum coherence in non-equilibrium entropy production (2017, background): “Tracing out the environment one obtains the Kraus map for the system ρS 1⁄4 trE UðρS ρ E ÞUy 1⁄4X μ;ν Mμ;νρSM y μ;ν (18) where Mμ;ν 1⁄4 ffiffiffiffiffi qμ p hνjUjμi.”
The role of quantum information in thermodynamics—a topical review (2015, background): “It is worth mentioning we can build necessary conditions for state transformations from these monotones, but sufficiency results are only known for classical states (states that are block-diagonal in the energy eigenbasis) [82] and any state of a single qubit [89, 90].”
Quantum resource theories (2018, background): “(27) (with the system S̃ being discarded), it can be seen that every thermal operation is time-translation covariant, i.e. [Φ,Ut] = 0 for all t (Lostaglio et al., 2015a).”
