Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

The double slit experiment reveals that observing light changes its behavior, making it act as both a wave and a particle.

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

Researchers replicated the classic double slit experiment using lasers, but their slits are in time not space. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

You can't see, feel, hear, taste or smell them, but tiny particles from space are constantly raining down on us.

Spencer Axani, assistant professor in the Department of Physics and Astronomy, is the inventor of CosmicWatch, a portable, ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...
