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 ...

MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings ...

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 interference pattern disappearing when the photon's path is detected. In the latest ...

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

This quantum balancing act—long debated by Einstein and Bohr—was tested without traditional “spring” components, instead relying on atomic “fuzziness” to confirm Bohr’s view: you can’t observe both ...

A groundbreaking quantum experiment conducted by MIT physicists has turned a major page in the long-standing debate between ...

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