Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

Whenever light interacts with matter, light appears to slow down. This is not a new observation and standard wave mechanics can describe most of these daily phenomena. For example, when light is ...

Back in 2000, a team of physicists led by Lijun Wang at the NEC Research Institute in Princeton, USA, pulled off a mind-bending experiment. They fired a precisely shaped laser pulse through a special ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

New observations of a far-flung galaxy cluster have left a group of scientists stumped as they ponder whether they’ve discovered a new form of physics. In their new paper, researchers Tessa Vernstrom ...
