Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

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

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

The double-slit experiment is the most famous and probably the most important experiment in quantum physics: individual particles are shot at a wall with two openings, behind which a detector measures ...

Antimatter isn't just made of antiparticles, it's also made of waves. Now we know that this holds true even at the level of a single antimatter particle. Physicists have known for a long time that ...
