Because the behavior of molecules and other large objects can be predicated with classic Newtonian physics it has been long thought that quantum effects did not influence them. Vlatko Vedral, in a June 2011 article published in Scientific American, writes that presently nearly all physicists think that quantum mechanics applies to everything regardless of size. It is difficult to observe the entangled states that exists in complex objects because it quickly fades. That is, it experiences decoherence. It appears that entanglements make up reality. Space and time emerge as a result of the decoherence of entanglements. An implication of this, that information is the fundamental element, is explored in his book, Decoding Reality, published last year.
Stuart Kaufman in Reinventing the Sacred and James Gardner in Biocosm explore related ideas.
Dr. Vedral also explores further ideas in a guest blog, where he explores how entanglement appears to allow for the deletion of information while not producing heat. That is, entanglement appears to make it possible to compute massive amounts of information without requiring massive amount so cooling.
