The double-slit experiment is already a head-scratcher for physicists. But now add this twist: Suppose that you have one barrier that can block one of the two slits. Is there a way to get that barrier to block both slits at once? In classical physics, the answer is no. But a new experiment reveals that it can be done in quantum physics. Japanese researchers created a "quantum shutter" that can block photons from passing through both slits.

What is double-slit experiment?
The modern double-slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles; moreover, it displays the fundamentally probabilistic nature of quantum mechanical phenomena.
