NOON state

Caption

A NOON state is a superposed quantum state where N particles are in one state "at the same time" and in another "at the same time". Here, the particles are trapped in two wells, within a trap formed by lasers. The superimposed state therefore consists of a state in which all the particles are in the left-hand well, and a state in which they are trapped in the right-hand well. The particles interact with each other and 'stick' together when they are in the same site, preventing an isolated particle from leaving the trap.
