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

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

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

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 ...

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 ...

MIT physicists perform the most precise double-slit experiment using ultracold atoms, confirming Bohr’s quantum theory over Einstein’s with groundbreaking clarity.

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

Like the proverbial tree falling in the forest, scientists wonder: does reality exist on its own . . . or just when you observe the world?

MIT’s quantum experiment validates Bohr’s theory and disproves Einstein’s local realism using ultracold atoms and single ...
