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

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

An international collaboration of researchers has achieved a significant breakthrough in quantum technology, with the successful demonstration of quantum interference among several single photons ...

The stunning experiment, which reconstructs the properties of entangled photons from a 2D interference pattern, could be used to design faster quantum computers. When you purchase through links on our ...

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

The interior of the vacuum chamber during a scattering experiment. The detector is shown in grey (top right) and the Au(111) gold surface is shown in yellow. The lines indicate the path of the ...

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 ...
