What about correlated Schrödinger's cats? What if we take the Schrödinger cat example one step further and instead of using a radioactive source and detector, use two boxes, two cats and a particle source which produces entangled particles? Here's an outline box1 >> cat1 >> detector1 >>...

Thanks ZapperZ - that's very helpful! I'll look for those articles (too bad they aren't on the arXiv or preprint).

There have been countless discussions about the thought experiment about Schrödinger's cat in a box, and how to describe the state of the cat before and after the box is opened, leading to all sorts of bizarre notions like a half dead/half alive cat inside the box, and I certainly don't fully...

I'm trying to understand the difference between the cloning of a quantum state (which is not allowed in QM) and a measurement. I have a specific example in mind, and am trying to make sense of it in terms of entropy and information transfer. Example (Based on Schrödinger's Cat): Consider two...

Nice paper! That's a very interesting and informative paper - thanks! Ed

I'll take a crack at this, but I'm sure you'll get some better answers soon ;) The question of what is light a wave in is a good question. First I'll address the classical view. The electric and magnetic fields of a light wave are what is waving so to speak. If you look at a picture of an...

Please let me know if this is the wrong place to post this question. I'm really fascinated by the idea of time symmetry in quantum mechanics and it's implications for the measurement process. I'm trying to make sense out of an article posted in the arXiv by Aharanov, et al. and it seems like...

This thread is based on some reading I've done on decoherence (a lot of it by Zurek) and recent experiments involving decoherence and complementarity. One interesting item is the recent experiment by Anton Zeilinger and team involving C60 molecules interacting to produce and interference pattern...
