How to choose the right Quantum Interpretation: Macrorealism, Contextuality and Decoherence

The next NWC will be held upcoming Friday 7th April at 6pm at the faculty of physics in Strudlhofgasse 4.

First, I would like you to revisit the materials from last time about Bells Inequality and local realism. Also Flavio already included nice material about Leggett-Garg Inequalities and macrorealism.

Second, here are my resources:

Level 1: I will cover basically the Legget-Garg and Kochen-Specker Theorems and how they could be experimentally tested to rule out certain QM Interpretations similar to Bell’s Inequality and local realism. A good starting point:

https://en.wikipedia.org/wiki/Kochen%E2%80%93Specker_theorem

Level 2: Kofler and Bruckner have written a nice comparison between Bell and L-G, also thinking about experiments that violate macrorealism:

And (my all-time favorite) Stanford Encyclopedia of Philosophy has a review over Kochen-Specker and it’s implications:

Level Experimental Metaphysics:
Well, in one meeting we probably won’t have time to cover more, but for the sake of completeness on experimental tests of quantum foundations, one has to add the current notion of decoherence as most promising solution to the measurement problem. Also this gives an idea why the many-worlds interpretation gains momentum right now.

Here is a recent overview of how decoherence relates to different interpretations:
