While waiting better answers from our resident physicists I'd like to make a comment of my own:
As I understand what I have read this idea of an "observation" implying an "observer" is a big misunderstanding. An observation is an interaction with something. It is the interaction which causes the quantum state to be determined. It doesn't require any "person" to be doing the "looking". Another particle can 'interact' and so 'observe' the state.
This is one (maybe the reason?) why the entanglement of things needed for quantum computing is so darned difficult to maintain. It isn't enough to have everyone in the room turn away and not peek. It is necessary that the entangled pair not interact with
anything.
