In this article there is a suggestion that the detectors "placed behind the screen" somehow detect through which slit the photons went, - detect some time after the photons passed the slits. But this is misleading! There are no such detectors. In the actual experiment the detection happen at the time the photons pass through the slits (before they hit the screen). Big difference.
