PS to tie my last post to Bohmian mechanics you could presumably include detector and environmental degrees of freedom so the states...

As the conversation has continued I'll post here. In Ma's actual experiment, the BiSA apparatus is interpreted as performing a...

I may save my responses to @PeterDonis for that thread as they are about the experiment in general rather than a Bohmian accounting.

Two points here: i) A run where no swap is attempted will leave 2 entangled with 1 and 3 entangled with 4. But a run where a swap is...

The less important issue: The state of A does change as it passes through the PBS The polarization degree of freedom becomes correlated...

It's common in consistent histories literature, where you are often chaining many projectors together. See e.g. equation (2) in...

To explicitly model* the measurement of 2 and 3 first, we would include the apparatus degrees of freedom and trace over them...

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.
