Quantum physics overturned classical ideas by showing that matter behaves very differently at the ...

Scientists review research on gravitational wave detectors as a historical example of quantum technologies and examine the fundamental research on the connection between quantum physics and gravity.

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral atom in a vacuum. Now, for the first time, we have observed quantum ...

Physicists have finally confirmed a phenomenon that sounds like pure science fiction: waves that appear to bounce off a sudden change in time rather than a surface in space. The effect, known 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 ...

Scientists have detected a strange new type of high-frequency wave on the sun's surface, and the waves are moving three times faster than scientists thought was possible. Scientists can't see into the ...
