Thanks for the response! Now this raises another question: In this experiment there is no interference without doing coincidence counting, but in the original double slit experiments the interference pattern is shown. So why is that, what is the difference between the two?

Thanks. I just read the article, very good by the way. So what I understand is that if you have any means to measure the which-path information (even if not measured yet), and you see the screen you will see the normal dist. If afterwards you erase the info from a subset of the photons, you...

Thanks guys for the response. Ok So let's see these 2 scenarios 1) I look at the screen AFTER completely erasing the which-path info of all photons. I see the interference pattern. right? 2) I look at the screen BEFORE completely erasing the which-path info of all photons. The idler...

I was reading about the Delayed Choice Quantum Eraser experiment here: bottomlayer.com/bottom/kim-scully/kim-scully-web.htm In this experiment the which-path info is erased or not at random AFTER the original (signal) photon hits the screen. The results of the screen are seen by the...
