Schrödinger Squared
An amped up version of the Schrodinger Cat Paradox spells trouble for all quantum interpretations -- according to its architect Renato Renner. He tells Zeeya and Brendan how the controversial thought experiment works, and why he thinks it is bad news for fans of Many Worlds and quantum parallel universes, QBism, Collapse models and (less so) for Bohmian interpretations of quantum mechanics. But not everyone agrees.

George,

We shouldn't conflate contradiction with inconsistency. QM has a dynamic track record not only of prediction in application to specific tasks, but also in discovery. Its worth noting that where we have seen discovery in QM it has been by theoretical regimes which are quasi-Relativistic, ie: inverse square law subject to Lorentz Invariance.

The question posed by Frauchiger and Renner, does contend inconsistency. But all the underpinning of QM parameters are classical laws...


Georgi,

by and large I agree. Near the end of the discussion panel, Aaronson summed it as what is proven is that we can prove QM is a theory. The 'why' that it works is omething that goes to vast numbers of events in the simplest macroscopic thing. A mature Maple tree in my neighborhood might produce 30,000 leaves in a season, yet there is still a small area way up in the wind where a few, scattered, dead leaves cling to their twigs in January. What are the odds of that, and what odds of...


Thanks for taking the time John. By 'relying on what they are sent' I mean what I think you are referring to as the 'classical record'.

Right now I'm thinking you can't make silk purse out of a sows ear. It starts out with quantum correlations and uses quantum maths and quantum explanations and ends up with something unexpected. I'm not sure if it is a true paradox, an impossibility (most likely indicating something wrong with the theory) or just what you get if you follow the...
