Physicists have taken quantum strangeness to an extraordinary new level by measuring light across 37 dimensions. Their groundbreaking experiment pushes quantum mechanics beyond classical expectations, ...

A new experiment confirms that photons passing through a cloud of atoms can spend a negative amount of time there, and the atoms themselves are the ones saying so.

TL;DR: This experiment may not revolutionize telecommunications, but it highlights how accessible these concepts have become outside traditional research labs. Using nothing more than an iPad, a solar ...

Researchers from Skoltech and the Shanghai Institute of Optics and Fine Mechanics have developed an approach that helps optimize the parameters of a laser-plasma source of attosecond pulses—ultrashort ...
