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 ...

(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 ...

“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 ...

Three's company: interference patterns for one to four slits (expand for full image) A group of physicists in Austria has directed a beam of large molecules at a series of extremely narrow slits to ...

In a first, scientists have shown that they can send light through “slits in time” in time. The new experiment is a twist on a 220-year-old demonstration, in which light shines through two slits in a ...

The double-slit experiment is the most famous and probably the most important experiment in quantum physics: individual particles are shot at a wall with two openings, behind which a detector measures ...

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 ...
