Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether ...

Physicists at MIT recreated the double-slit experiment using individual photons and atoms held in laser light, uncovering the true limits of light’s wave–particle duality. Their results proved ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...
