On the upper bound of classical correlations in a bipartite quantum system
For a bipartite quantum system consisting of subsystems A and B it was shown by Zhang et al. (Physics Letters A 376 (2012) 3588-3592) that the amount of classical correlations, which is used to
Upper Bounds for the Holevo Information Quantity and Their Use
TLDR
It is shown that an appropriate choice of the reference state gives tight upper bounds for the Holevo quantity which in many cases improve the estimates existing in the literature.
Upper bounds for the Holevo quantity and their use
TLDR
It is shown that appropriate choice of the reference state gives tight upper bounds for the Holevo quantity which in many cases improve existing estimates in the literature.
Internal Entanglement and External Correlations of Any Form Limit Each Other.
TLDR
The internal entanglement of a bipartite system, and its correlations with another system, limit each other, and a measure of correlations, of any nature, cannot increase under local operations.

On conjectures of classical and quantum correlations in bipartite states
In this paper, two conjectures which were proposed in Luo et al (2010 Phys. Rev. A http://dx.doi.org/10.1103/PhysRevA.82.052122) on the correlations in a bipartite state ρAB are studied. If the
Matrices of fidelities for ensembles of quantum states and the holevo quantity
TLDR
This work combines geometrical and probabilistic aspects of the ensemble in order to obtain meaningful bounds for χ by constructing various correlation matrices involving fidelities between every pair of states from the ensemble.
Universal bounds for the Holevo quantity, coherent information, and the Jensen-Shannon divergence.
TLDR
Using strong subadditivity of entropy, it is proved that the Holevo quantity is not larger than an exchange entropy, which implies an upper bound for coherent information.
