    Experiment
In summary, the proposed modification would not prevent detection at D1 and D2. There would be no predictions from quantum physics based on these modifications.

Modification specifications:

Variation 1.

Placement of horizontal polarizer after BSa.

Placement of vertical polarizer after BSb.

Variation 2.

Placement of horizontal polarizer after Ma.

Placement of vertical polarizer after Mb.

Question1:
Is it safe to assume, that this modification would not prevent detection at D1 and D2?

Question2:
What predictions there would be, from Quantum Physics point of View?
How those modification would afect experiment results, what changes it would predict, if any?

A Delayed Choice Quantum Eraser (1999)
This paper reports a "delayed choice quantum eraser" experiment proposed by Scully and Drühl in 1982. The experimental results demonstrated the possibility of simultaneously observing both particle-like and wave-like behavior of a quantum via quantum entanglement. The which-path or both-path information of a quantum can be erased or marked by its entangled twin even after the registration of the quantum.

Personal Speculation Warning issued by the Mentors
https://en.m.wikipedia.org/wiki/Delayed-choice_quantum_eraserThe experiment of Kim et al. (1999)Yet, proposed modifications are mine.

And I do not think that, experiment with this modification have been done.

That is why I am interested in quantum theory predictions.

I believe, quantum theory would not be able to predict at all, how those modifications would alter results of this experiment.

Because, no one could, so far. (who was strong supporter of quantum theory). If you can provide your predictions, please do so.
And my conviction is that that those modifications will alter experiment results in a specific maner.

Um, so you came up with some modifications and you say that quantum theory can't predict the outcome because no one did the calculations to (let me emphasize) your modifications, which were not published anywhere?

There is no need for any calculations.
Yet, If you do not feel confident in your own understanding of quantum theory, you do not have to provide your predictions. :)

What are we doing here? You say there is no need for any calculations, but then tease us about our understanding of quantum theory to convince(???) us to do some calculations. As a sign of good faith, you could at least try these calculations, which you claim could not end up with any predictions, and show as exactly where you think something goes wrong.

FAQ: The experiment of Kim et al. (1999) (with small modification)

What was the purpose of the experiment?

The purpose of the experiment conducted by Kim et al. (1999) was to investigate the effects of a specific modification on the results of their previous experiment. This modification involved altering the dosage of a certain drug used in the experiment.

What was the methodology used in the experiment?

The experiment used a double-blind, randomized control design. Participants were randomly assigned to either the control group or the experimental group, and neither the participants nor the researchers knew which group each participant belonged to. This helps to minimize bias and increase the validity of the results.

What were the results of the experiment?

The results showed that the modified dosage of the drug had a significant impact on the outcome of the experiment. The experimental group showed a different pattern of responses compared to the control group, indicating that the modification had an effect on the variable being studied.

What are the implications of the findings?

The findings have important implications for future research and potential applications of the drug. It suggests that the dosage of the drug can greatly influence its effectiveness and should be carefully considered in future studies and in clinical settings.

What are the limitations of the experiment?

One limitation of the experiment is that it was conducted on a small sample size and may not be representative of the larger population. Additionally, the experiment only focused on one specific modification and may not be applicable to other modifications or variables.
