Hi,

The most recent article that covers the entire topic of entanglement is:

Quantum entanglement , Rev. Mod. Phys. 81, 865 (2009), by Horodecki et al.

You can find it here:

http://journals.aps.org/rmp/abstract/10.1103/RevModPhys.81.865

Or a less updated free version here:

http://arxiv.org/abs/quant-ph/0702225

As this article is more than 100 pages long, I believe it contains answers to your questions.

I hope it helps,

Assaf

Many thanks, Assaf!
