Measures of Quantum Entanglement  

In General > s.a. entanglement; quantum correlations.
* Idea: Two approaches to entanglement measures are a geometric one and one based on fidelity; The standard geometric entanglement measure for a pure state is sin2θ, where θ is the angle between the state and the closest separable (unentangled) one.
