A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

Several weeks ago I picked up “The Elegant Universe” because I thought it would have information on The Ultimate Theory. Soon afterwards, I picked up “How to Teach Physics To Your Dog” in order to get ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

The classic double-slit experiment of quantum physics involves shining light through two narrow gaps to show that it can behave as a wave – now it seems the slits can be entirely replaced by a single ...
