I am criticizing the interpretation of the results of the delayed choice quantum erasure double slit experiment. The authors claimed that the results prove that the "which way" information is "erased" in-line with the theory of Quantum Mechanics and the theory on partial-wave duality. I am exposing the flaw in the results. The flaw is that the signal photon merely tells you whether or not the idler photon produces an interference pattern and thus the results are meaningless. The fact is that the which-way information is present and never erased with the idler photon, thus you do not need to consider the signal photon at all. The idler photon has two different paths that are split and recombined for each slit. As an interference pattern is observed when doing this, it is therefore correct that if you had the use of a precise enough stopwatch and you timed the time it takes the photon to complete its journey you obtain the which way information - completely passively - without disrupting the interference pattern. No entanglement, no complications.
The theory on wave-partial duality is totally wrong, FYI.
The experiment was designed to show that when the experimenters looked only at the signal photons whose entangled idlers were detected at D1 or D2 - where we know that signals came from both slits - they found an interference pattern.
However, when they looked at the signal photons whose entangled idlers were detected at D3 or similarly at D4 - where we know the beams came from either the upslit or the downslit - they found no interference.
You will find that this is exactly the same result from the link I have given to you.
