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

A new version of the famous double-slit experiment showed that it's impossible to measure light as both a wave and a particle ...

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

It's time for the latest update in confirming things we already knew—and, as always, it's being far more interesting than you ...

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

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

This quantum balancing act—long debated by Einstein and Bohr—was tested without traditional “spring” components, instead ...

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

For nearly a hundred years, one of the most celebrated minds in science, Albert Einstein, had a lingering quantum thought ...

In a striking display of quantum physics, a team of researchers has recreated one of science’s most legendary ...
