Heisenberg limit gets a meaningful update

One of the cornerstones of quantum theory is a fundamental limit to the precision with which we can know certain pairs of physical quantities, such as position and momentum. For quantum theoretical treatments, this uncertainty ...

Researchers demonstrate optical backflow of light

Researchers at Tel Aviv University have for the first time demonstrated the backflow of optical light propagating forward. The phenomenon, theorized more than 50 years ago by quantum physicists, has never before been demonstrated ...

Physicists see nuclear wobbling in one isotope of gold

Nuclei can be round, like a soccer ball, or oblong, like a football. Others are slightly oblong but misshapen, like a potato. One of the only two ways to observe the third shape, rarely encountered, is when the nucleus wobbles ...

What if we could teach photons to behave like electrons?

To develop futuristic technologies like quantum computers, scientists will need to find ways to control photons, the basic particles of light, just as precisely as they can already control electrons, the basic particles in ...

Quantum computers offer another look at classic physics concepts

"Think what we can do if we teach a quantum computer to do statistical mechanics," posed Michael McGuigan, a computational scientist with the Computational Science Initiative at the U.S. Department of Energy's Brookhaven ...
