A carefully designed experiment uses Hardy’s paradox to illustrate lack of local realism. Hardy’s 30-year-old thought exercise has led many researchers to chip away at real versions. If the universe ...

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 ...
