“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

In the future, quantum computers are anticipated to solve problems once thought unsolvable, from predicting the course of ...

In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

For the first time, scientists have observed quantum interference—a wavelike interaction between particles related to the weird quantum phenomenon of entanglement—occurring between two different kinds ...

Physicists at the University of Stuttgart, Germany have teleported a quantum state between photons generated by two different ...

The interior of the vacuum chamber during a scattering experiment. The detector is shown in grey (top right) and the Au(111) gold surface is shown in yellow. The lines indicate the path of the ...

For the first time, researchers from Tokyo University of Science have observed wave-like interference patterns from ...
