It seems quantum mechanics systematically refuses to properly model the "observer". As in: mathematically quantum model of the large and complex experimental setup that tries to "measure" something, including the observer.
It's probably not done because it's too hard, but the day they do this and actually include it in any equations that try to describe a system, I suspect much clarity will ensue.
- eigenket 6y agoIf you do that (at least with the approaches I've seen) and follow "standard" quantum mechanics rules for the observer as well as the observed the you end up deriving many worlds / Everettian quantum mechanics.
- d_tr 6y agoIt is AFAIK a very standard approach to treat two interacting quantum systems (e.g. two electrons) as "measuring" each other and work with density matrices and partial traces to see how the "measurement" is evolving and what is each system "seeing". You might be interested in learning about the field of quantum decoherence.
