WebA dynamical map Λtrepresents a Markovian evolution if Λtis CP-divisible. In Ref. [25], Breuer et al proposed another approach to define Markovianity, based on the distinguishability of quantum states under a quantum dynamics. Namely, the information flow of a dynamical map Λt has been introduced for a pair of initial states ρ1 and ρ2, Webization yield through non-Markovian e ects beyond val-ues achievable in the Markovian regime [63]. Within this framework the state transformations due to coupling to the heat bath are described by means of so-called ther-mal operations, i.e., energy preserving unitary opera-tions U acting on the system and the bath; the con-
