I forgot about B. Before A is detected, the state of B is the usual ##\mathrm{tr}_\mathrm{A}\ket{\Phi^+}_\mathrm{AB}##. After A is...

The state of A before it passes through the PBS would be ##\mathrm{tr}_\mathrm{B}\ket{\Phi^+}_\mathrm{AB} =...

The difference in ordinary QM would be in theirs states. If the state of A+B before they arrive at their respective detectors is...

If you are carrying out the textbook standard QM calculation of unitary evolution -> measurement -> collapse (preparation) -> unitary...

In the other thread, @DrChinese says: "Show me any Bohmian step by step explanation of the mechanics - in precise time order as required...

Write down the initial wavefunction of the entangled particles and observing environment. ##|\Psi(0)\rangle =...

It looks like a generalization of the "dictionary" account of the stochastic matrix. Similar to the general form here: [edit] - Not to...

Disabusing people of notions like everything is made of energy is well within the wheelhouse of physicists.

fwiw a skim of literature shows papers that resolve Bohmian trajectories from weak measurements. E.g. https://arxiv.org/abs/0706.2522

The issue is it is introduced as a principle. An argument that justifies it via Mott scattering would be an interesting discussion. I am...

Why? Couldn't an ensemble of tracks reproduce probability current direction without each track individually adhering to that direction...

Systems are not made of energy. Energy is a property of systems. It would be like saying apples are made of redness.

Is this supported by textbook QM?

Different subsystems will have different dynamics, so the choice of division into subsystems will yield different subsystems and hence...

Assuming the Wigner superobserver performs some recoherent operation analogous to a quantum eraser experiment: If by "Does a division...
