Physics team entangles photons that never coexisted in time
Scientists cast doubt on renowned uncertainty principle
Werner Heisenberg's uncertainty principle, formulated by the theoretical physicist in 1927, is one of the cornerstones of quantum mechanics. In its most familiar form, it says that it is impossible to measure ...

'Groovy' hologram creates strange state of light at visible and invisible wavelengths
(Phys.org) —Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated that they can change the intensity, phase, and polarization of light rays using a hologram-like ...
Swirls in remnants of big bang may hold clues to universe's infancy
South Pole Telescope scientists have detected for the first time a subtle distortion in the oldest light in the universe, which may help reveal secrets about the earliest moments in the universe's formation.
