Özet

A general property of quantum coherence and quantum correlations is its non-increasing behavior during any incoherent quantum operation, such as an incoherent quantum channel in a noisy environment. We address that thermal coherence and correlations can mitigate these losses by offering relative improvements for different quantum models constructed with the quantum Yang–Baxter matrix. In particular, it is possible to obtain the thermal coherence of thermal density operators obtained by Hamiltonians, even for higher temperatures and certain values of the other parameters compared to other models. By adjusting the parameters, it is maximized such that the state of the output is maximally coherent. These make it possible to create maximal coherence in realizing any quantum information task in a noisy environment.
