Entanglement and Agreement and What’s Underneath?

Apr 09, 2012 Posted Under: physics

While reading the Quantum Reality article in last week’s ScienceNews, I was inspired to dig a little deeper and found this review of work by G. Chiribella, G. D’Ariano, and P. Perinotti last year. It points up a fundamental flaw in my previous attempts to understand quantum mechanics — that there are “events” and “observers”.

It now becomes obvious that a more consistent framing would be that of an “experience” in which both observed and observer participate.  Similarly, two “observers” could only have the closest possible agreement about what happened if they both particpate in the experience of an observation simultaneously, as part of a system of 3.

Thus agreement about an experience of events below some certain macro collection of quantum probabilities is practically infeasible.  This is a different framing of Heisenberg’s Uncertainty Principle, that you can’t increase to arbitrary precision the measurements of certain pairs of properties.

This supports the previous estimate that usable agreements require the organizational complexity we usually call life.

I am still perplexed at how information maps onto anything we call space or matter.

But at least now the next framework for posing these questions looms into clearer view …
