Exotic paths: artist's impression of the microwave triple-slot experiment. Courtesy: G Rengaraj et al/New Journal of Physics) The importance of including exotic “non-classical paths” in analyses of ...

Scientists show helium atoms can exist in two places at once, preserving quantum behavior even as they fall under gravity.

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

Imagine asking the biggest, most fundamental question of all: what is reality? How would you go about answering it? If you took the scientific approach, you'd go down to the smallest indivisible ...

Physicists in Europe and the US have performed a novel version of the double-slit quantum-interference experiment with single electrons. In the classic version of the experiment, electrons pass ...

“Einstein and Bohr would have never thought that this is possible, to perform such an experiment with single atoms and single photons,” said Wolfgang Ketterle, head of the MIT group whose new ...

(Inside Science) — One of the strangest things about quantum mechanics is that a particle can act like a wave. In particular, in a double-slit experiment, individual particles that are shot through a ...

Scientists recreated one of the most important experiments in the history of physics—but this time, they used antimatter instead of regular matter. All matter particles have a corresponding antimatter ...
