Atomic “bomb testing”: the Elitzur–Vaidman experiment violates the Leggett–Garg inequality (2016)
Journal Article

Elitzur and Vaidman have proposed a measurement scheme that, based on the quantum superposition principle, allows one to detect the presence of an object—in a dramatic scenario, a bomb—without interacting with it. It was pointed out by Ghirardi that... Read More about Atomic “bomb testing”: the Elitzur–Vaidman experiment violates the Leggett–Garg inequality.
