Light is everywhere,it illuminates our world, enables vision, and travels across galaxies. But what is light, really? Is it a ...

Physicists at MIT recreated the double-slit experiment using individual photons and atoms held in laser light, uncovering the ...

MIT researchers used ultracold atoms to isolate the quantum trade-off between wave interference and particle path detection.

Light behaves like a continuous wave, but it also has the properties of a particle. So which is it? Dr Matt Middleton from Southampton University, UK, uses the sea as a metaphor to explain how it ...

The interference of the scattered light is recorded with a highly sensitive camera depicted as a screen. Incoherent light ...

The experiment showed that Bohr was definitely correct when he argued for complementarity, and that Einstein had got it wrong. The more atom-rustling that was measured, the weaker the diffraction ...

Einstein wasn’t satisfied. At a 1927 conference, he suggested a way to catch light in both modes. If you could detect the ...

Unfortunately for Einstein, all work done subsequently – including experiments that used springs – does point to the ...

A groundbreaking experiment demonstrates yet again that light exists both as a wave and a particle in the quantum world—but ...
