Researchers have finally resolved a century-old debate over the famous "double slit" experiment, according to new research.

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

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

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

Left, schematics of the apparatus (positron beam, collimators, SiN gratings and emulsion detector. A HpGe detector is used as beam monitor). Right, single-particle interference visibility as a ...

One of the most important experiments of quantum physics gets a makeover: When neutrons are fired at a crystal, they can be made to travel along two paths at the same time. Until now, this was only ...
