DOI: 10.1038/s41598-017-13687-4
Abstract: We investigate the single qubit transformations under several typical coherence-free operations, such as, incoherent operation (IO), strictly incoherent operation (SIO), physically incoherent operation (PIO), and coherence-preserving operation (CPO). Quantitative connection has been built between IO… read more here.

Abstract: According to Clausius formulation of the second law of thermodynamics, for any thermal machine withdrawing heats ${Q}_{1,2}$ from two heat reservoirs at temperatures ${T}_{1,2}$, it holds that ${Q}_{1}/{T}_{1}+{Q}_{2}/{T}_{2}\ensuremath{\le}0$. Combined with the observation that the quantity… read more here.
