Quantum coherence, discord and correlation measures based on Tsallis relative entropy
Anna Vershynina
Several ways have been proposed in the literature to define a coherence measure based on Tsallis relative entropy. One of them is defined as a distance between a state and a set of…

Upper continuity bound on the quantum quasi-relative entropy
Anna Vershynina
We provide an upper bound on the quasi-relative entropy in terms of the trace distance. The bound is derived for two cases: 1) any operator monotone decreasing function and full ra…
