TL;DR Summary
Quick question about relationship between QM and general relativity
The wave function includes coordinates for position in space. For two distant but correlated particles, do their distances and paths of movement used in the wave function follow the curved space-time of general relativity, or is Euclidean distance assumed in QM?

I support neither of your idea : Eucledian distance does not fit with GR and classical curved space-time doe s not seem fit with QM. If you could get an answer, you would be honerd as a pioneer of quamtum gravity.

Here you are using non-relativistic QM.

Here you are trying to use relativity, which means you can't use non-relativistic QM. You have to use quantum field theory, and in curved spacetime to boot, in which there is no such thing as a "wave function". That's not how QFT models things.

There are no such things even in non-relativistic QM. The wave function does not describe "distances and paths of movement".

No. In quantum theory on curved spacetime, a curved geometry is used.

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
