Researchers have shown that surprisingly large metal particles can behave according to quantum mechanics, existing in ...

A team of physicists has shown that pairs of helium atoms, chilled to near absolute zero and launched into each other, can ...

Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Physicists at the Australian National University have observed pairs of atoms existing in two places at once for the first time, a result that extends one of quantum mechanics’ strangest properties ...

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 ...

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 ...

The famous double slit experiment shows that particles can travel on two paths at the same time -- but only by looking at a lot of particles and analysing the results statistically. Now a ...

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 ...
