Entanglement and decoherence: middle-brow treatment?

    I'm a physicist, but I'm not a specialist in the foundations of quantum mechanics. This month's Scientific American has an article by Vlatko Vedral about entanglement and decoherence.

    Paywalled article, with a brief summary: http://www.scientificamerican.com/article.cfm?id=living-in-a-quantum-world

    The article is so easy that I can't understand it. In other words, it's watered down so much for a general audience that I can't even extract any meaning from it. On the other hand, I suspect that I wouldn't be able to follow a "real" paper on this topic. Does anyone know of a good discussion of this kind of thing that's at a middle-brow level?

    Some things from the paper that seemed interesting but that were described too vaguely for me to make anything of them:

    -work by Aeppli, 2003, measuring the magnetic properties of a macroscopic salt crystal as a function of temperature

    -work by Ritz, 2000, and by Vedral claiming that European robins sense magnetic fields using a system in which entanglement persists for 10^-4 s, which he apparently interprets to mean that a macroscopic biological system can really be in a superposition of states, like Schrodinger's cat

    Scientific American is not what it used to be.
