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

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

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

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 ...

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

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

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

The concept of light has fascinated scientists for centuries. A recent MIT experiment has reignited the debate about its dual nature. The MIT team revisited a classic experiment with ...

Physicists have discovered that when beams of light interact at the quantum level, they can generate ghost-like particles ...

For a chosen electron and positron velocity of 100 meters/second, for example, the de Broglie wavelength is 7.28 microns.

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

Light can behave in very unexpected ways when you squeeze it into small spaces. In a paper in the journal Science, Mark ...
