The Quantum Mechanics of Experiments

[Morbert]

TL;DR

New paper by Froehlich on the ETH-approach to QM with a focus on the measurement problem.

A paper some people might find interesting: https://arxiv.org/abs/2603.25335

Froehlich's work has come up a few times here (E.g. https://www.physicsforums.com/threa...e-deeper-meaning-of-quantum-mechanics.972179/ ). It's a stochastic, histories based approach, but centers operator algebras in the presentation so is not as approachable as other interpretations.

The recent paper applies it to the measurement problem and the double-slit experiment as an example.

I was complaining about noone taking the Montevideo interpretation seriously (yes I know it an interpretation and, as such, a well and truly flogged horse; close to death in fact.) But as someone said to me the MV I of QM is more than that, and this one even talks about experiments?!!

Without having read it all (those who know me wont be surprised that I express an opinion before I've read it all, it's a really really bad habit of mine), it looks like once again time is the problem. They articulate it differently granted, but let us introduce real clocks! (and watch them turn into black holes! )
