Relative entropy and catalytic relative majorization [PDF]

open access: yesPhysical Review Research, 2020
Given two pairs of quantum states, a fundamental question in the resource theory of asymmetric distinguishability is whether there exists a quantum channel converting one pair to the other.

Relative Entropy in CFT

open access: yesAdvances in Mathematics, 2017
By using Araki's relative entropy, Lieb's convexity and the theory of singular integrals, we compute the mutual information associated with free fermions, and we deduce many results about entropies for chiral CFT's which are embedded into free fermions ...

Entanglement entropy, relative entropy and duality [PDF]

open access: yesJournal of High Energy Physics, 2019
A definition for the entanglement entropy in both Abelian and non-Abelian gauge theories has been given in the literature, based on an extended Hilbert space construction.

Relative Entropy Derivative Bounds [PDF]

open access: yesEntropy, 2013
We show that the derivative of the relative entropy with respect to its parameters is lower and upper bounded. We characterize the conditions under which this derivative can reach zero.

Tight bound on relative entropy by entropy difference [PDF]

open access: yesIEEE Transactions on Information Theory, 2015
We prove a lower bound on the relative entropy between two finite-dimensional states in terms of their entropy difference and the dimension of the underlying space.

All Inequalities for the Relative Entropy [PDF]

open access: yesCommunications in Mathematical Physics, 2005
The relative entropy of two n-party quantum states is an important quantity exhibiting, for example, the extent to which the two states are different. The relative entropy of the states formed by reducing two n-party to a smaller number $m$ of parties is

An Integral Representation of the Relative Entropy [PDF]

open access: yesEntropy, 2012
Recently the identity of de Bruijn type between the relative entropy and the relative Fisher information with the reference moving has been unveiled by Verdú via MMSE in estimation theory.

Relative Entropy and Torsion Coupling [PDF]

open access: yesPhysical Review D, 2016
We evaluate the relative entropy on a ball region near the UV fixed point of a holographic conformal field theory deformed by a fermionic operator of nonzero vacuum expectation value.

Relative entropy and holography [PDF]

open access: yesJournal of High Energy Physics, 2013
Relative entropy between two states in the same Hilbert space is a fundamental statistical measure of the distance between these states. Relative entropy is always positive and increasing with the system size. Interestingly, for two states which are infinitesimally different to each other, vanishing of relative entropy gives a powerful equation $ΔS=ΔH$
