Abstract
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.
期刊介绍：
The aims of this peer-reviewed online journal are to distribute and archive all relevant material required to document, assess, validate and reconstruct in detail the body of knowledge in the physical and related sciences.
The scope of EPJ Plus encompasses a broad landscape of fields and disciplines in the physical and related sciences - such as covered by the topical EPJ journals and with the explicit addition of geophysics, astrophysics, general relativity and cosmology, mathematical and quantum physics, classical and fluid mechanics, accelerator and medical physics, as well as physics techniques applied to any other topics, including energy, environment and cultural heritage.
