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

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two centuries, the double-slit experiment has been providing a direct visual ...

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of ...

Nearly a century after Albert Einstein and Niels Bohr turned a technical disagreement into a philosophical duel, a new ...

A groundbreaking experiment demonstrates yet again that light exists both as a wave and a particle in the quantum world—but we can’t see both at the same time. Reading time 3 minutes Albert Einstein ...

In quantum world, particles like photons can behave like particles (localized points) or waves (spreading out, showing interference patterns). The classic double-slit experiment is a good ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

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 ...
