For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew. When you purchase through links on our site, we may earn an ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

The quantum rules shaping molecular collisions are now coming into focus, offering fresh insights for chemistry and materials science. When molecules collide with surfaces, a complex exchange of ...

Specifically, the study uncovers a new form of quantum interference in molecule scattering. Unlike the more familiar "diffractive" interference that affects scattering angles (as in the double-slit ...
