Two Paths at Once: Watching the Buildup of Quantum Superpositions

Scientists observe how quantum superpositions build up in a helium atom within femtoseconds. Just like in the famous double-slit experiment, there are two ways to reach the final outcome.

When a laser pulse transfers enough energy to one of the electrons in the helium atom, the electron is ripped out of the…
