Creating schrödinger-cat states

Using a single atom in a cavity to control a propagating optical pulse can deterministically create a Schrödinger-cat state — an intriguing quantum superposition of classically distinct

states. The result is a new opportunity for quantum state engineering with potential applications in quantum networks and computation. Access through your institution Buy or subscribe This
