Quantum mechanics has always had a way of making even the sharpest minds stop and scratch their heads. In the everyday world, you expect objects to follow straightforward rules. A ball thrown into the ...

A team of quantum physicists has taken a concept that once lived purely in equations and turned it into hardware reality, creating a single particle of light that behaves as if it occupies 37 distinct ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone of technologies that shape our lives, from lasers and microchips to quantum ...

Physicists have pushed one of the strangest ideas in science into new territory, holding tiny clumps of metal in a quantum limbo that recalls Schrödinger’s famous cat. Instead of a single atom or ...

Breaking the time asymmetry remains a fundamental yet tantalizing scientific challenge. At the macroscopic level the quest has so far turned out to be fruitless, but on the other hand in the subatomic ...
