Quantifying coherence.
A rigorous framework for the quantification of coherence is introduced and classes of functionals that satisfy defining conditions that satisfy these conditions are identified and other, at first glance natural quantities, that do not qualify as coherence measures.
An introduction to entanglement measures
The theory of entanglement measures is reviewed, concentrating mostly on the finite dimensional two-party case, and an exteneive list of open research questione will be presented.
Quantifying Entanglement
We have witnessed great advances in quantum information theory in recent years. There are two distinct directions in which progress is currently being made: quantum computation and error correction
Entanglement and non-markovianity of quantum evolutions.
Two different measures of non-markovianity are introduced that exploit the specific traits of quantum correlations and are suitable for opposite experimental contexts when complete tomographic knowledge about the evolution is available and when no information whatsoever is available.
Colloquium: quantum coherence as a resource
The coherent superposition of states, in combination with the quantization of observables, represents one of the most fundamental features that mark the departure of quantum mechanics from the
Colloquium: Area laws for the entanglement entropy
Physical interactions in quantum many-body systems are typically local: Individual constituents interact mainly with their few nearest neighbors. This locality of interactions is inherited by a decay

It is proven that logarithmic negativity does not increase on average under a general positive partial transpose preserving operation (a set of operations that incorporate local operations and classical communication as a subset), which is surprising, as it is generally considered that convexity describes the local physical process of losing information.
Dephasing-assisted transport: quantum networks and biomolecules
Transport phenomena are fundamental in physics. They allow for information and energy to be exchanged between individual constituents of communication systems, networks or even biological entities.
The Quantum jump approach to dissipative dynamics in quantum optics
Dissipation, the irreversible loss of energy and coherence, from a microsystem, is the result of coupling to a much larger macrosystem (or reservoir) which is so large that one has no chance of
Entanglement-Assisted Local Manipulation of Pure Quantum States
We demonstrate that local transformations on a composite quantum system can be enhanced in the presence of certain entangled states. These extra states act much like catalysts in a chemical reaction:
