I think it's really cool that you've been using this detailed author contribution system - hope you keep doing it despite the headache and that it inspires other PIs!

Is one way to think about Axiom 2, the idea that the classical world continuously monitors the quantum world, which back-reacts onto it?

Quite cool to see this error correction angle! Nice workl

How long do we have to keep pretending that studying random unitaries teaches us about black holes?

Good first Q (what part of community do you identify with)

I wanna know what the community expects of different author positions and also from people in different roles PIs, post docs, etc

+ what do people want ideally

Ofc these are fluid and vary project to project but maybe there are trends!

In this sense we agree because the probability of which outcome is "actualised" is due to the Born rule. And how to get that out of your theory is i think the hard part.

Shout out to the great Tony Short who gave this a go

Probability in many-worlds theories

I think any process that makes the information on the diagonal of a quantum states "easier to access" requires decoherence. One could then ask where does this decoherence stem from, randomness or some entropically motived argument.

Why? Measurement is the dynamical objectification of the classical information of quantum states into larger and larger systems.

One can get this dynamics randomly a la Zurek or thermodynamically arxiv.org/abs/2302.11253

I think explaining why we observe the Born rule is the hard part.
Quantum measurements and equilibration: the emergence of objective reality via entropy maximisation
Textbook quantum physics features two types of dynamics, reversible unitary dynamics and irreversible measurements. The latter stands in conflict with the laws of thermodynamics and has evoked debate ...

This is sick ❤️

Please do add this to the scirate comment thread to reinvigorate the discussion over there.

And thanks for the patience for actually going through a paper and thinking through its core assumptions and reporting back.

I think this is really lacking in our scientific culture

Congratulations @perp-waterfall.bsky.social ! Your PhD journey and the results you've obtained during that journey are definitely inspiring.

All the best for what's to come ✌️
