The quantification of quantum entanglement is a central issue in quantum information theory. Recently, Gao \emph{et al}. ( \href{this http URL}{Phys. Rev. Lett. \textbf{112}, 180501 (2014)}) pointed out that the maximum of entanglement measure of the permutational invariant part of $\rho$ ought to be a lower bound on entanglement measure of the original state $\rho$, and proposed that this argument can be used as an additional requirement for (multipartite) entanglement measures. Whether any…

An answer to a question of Gudder about the existence of optimal pure state ensembles
Gudder, in a recent paper, defined a candidate entanglement measure which is called the entanglement number. The entanglement number is first defined on pure states and then it extends to mixed


Geometric measure of entanglement and applications to bipartite and multipartite quantum states
The degree to which a pure quantum state is entangled can be characterized by the distance or angle to the nearest unentangled state. This geometric measure of entanglement, already present in a
Measuring Coherence with Entanglement Concurrence
This work proposes a new valid quantum coherence measure, coherence concurrence, which is a convex roof measure, for a quantum system of arbitrary dimension, essentially using the generalized Gell-Mann matrices.
Intrinsic randomness as a measure of quantum coherence
Based on the theory of quantum mechanics, intrinsic randomness in measurement distinguishes quantum effects from classical ones. From the perspective of states, this quantum feature can be summarized
Measure of multipartite entanglement with computable lower bounds
A measure of multipartite entanglement, k-ME concurrence, that unambiguously detects all $k-nonseparable states in arbitrary dimensions that is experimentally implementable without quantum state tomography and easily computable as no optimization or eigenvalue evaluation is needed.
Mixed-state entanglement and quantum error correction.
It is proved that an EPP involving one-way classical communication and acting on mixed state M (obtained by sharing halves of Einstein-Podolsky-Rosen pairs through a channel) yields a QECC on \ensuremath{\chi} with rate Q=D, and vice versa, and it is proved Q is not increased by adding one- way classical communication.
On the characterization of entanglement
In the context of N-party composite systems some considerations about entanglement magnitudes defined on the set of their states are made. A minimal set of necessary and sufficient requirements any
Volume of the set of separable states
The question of how many entangled or, respectively, separable states there are in the set of all quantum states is considered. We propose a natural measure in the space of density matrices %
Convex-roof extended negativity as an entanglement measure for bipartite quantum systems
We extend the concept of negativity, a good measure of entanglement for bipartite pure states, to mixed states by means of the convex-roof extension. We show that the measure does not increase under

A powerful theorem is proved which states what kind of (possibly mixed) bipartite states or distributions of bipartites states cannot be remotely prepared, and an upper bound on the amount of G-concurrence that can be created between two single-qudit nodes of quantum networks by means of tripartite RED is established.
Operational one-to-one mapping between coherence and entanglement measures
We establish a general operational one-to-one mapping between coherence measures and entanglement measures: Any entanglement measure of bipartite pure states is the minimum of a suitable coherence
