Ok I can definitely agree with this. Only, in this case we go back to the original question: what is "weird" about the quantum eraser experiment? The explanation you posted is similar to the one I gave at the beginning: I mean, if it is like this the appereance and the disappereance of the...

As I see it, but of course I might be wrong, they have an active effect in this case: Case 1 (polarizers over the slits): the photon will pass through both of them, overcoming the slits, and (exactly because it passed through the polarizers) it will find itself in a superposition state of H...

I agree, this is indeed the sense of the experiment. But what I am saying is that if you place the polarizers before the slits this explanation doesn't work because the disappereance of the pattern will be dependent on an active distruptive effect of the device used not on the...

But if you place polarizers before the slits then it will be "normal" not to observe an interference pattern. The photon will pass just through one slit instead of two as it would have done without polarizers. Namely, it would be our measurement device which would have force the photon to go...

Hi guys, I managed to find an explanation of the experiment given by the author himself on his blog. I am sorry I didn't manage to find it before. Apparently he was answering a guy who had my same doubts about the quantum eraser experiment. In particular he too pointed out how the...

Hi, but, as you said, if we have a wavefunction passing through two slits we should have an interference pattern. Therefore, how is that possible that when we put a measuring device (wheter it is possible or not to effectively measure the which way information) this interference will not...

I don't know anything about the delayed-choice experiment, so I cannot say anything on that. In the case of the quantum eraser, however, I think you are misinterpreting what it tells us: what is surprising is that when you put a device (such as the ulterior 45° polarizer in my formulation of...

If I understood correctly what your reference says is that the photo paper we had from the past experiment will "magically" change from a scatter pattern to an interference pattern right? Again, I am a novice but I think this is incorrect and not the sense of the quantum eraser experiment...

Thank you guys, It is different, the one you posted involves entangled photons which are sent into two different directions. Well, I would not confidently say that this is what the author of the book thinks. As I said I am a complete novice to the topic so it is very likely that if there...

Thank you Stevie! So, if I got it right, the photon passes through both the polarizers and it goes into a superposition state of V and H polarization (thus producing an interference pattern) but this only happens when there is something (the extra polarizer in this case) that erases the...

Hello everybody, I am absolutely a novice in physics and although I generally have a good grasp of math I am pretty sure my knowledge of it is quite far from the one required by quantum physics. However, I am very interested to its main concepts and for this reason I am reading an...
