Observation of collective excitation of two individual atoms in the Rydberg blockade regime
Abstract
When two single Rydberg atoms—those with electrons in highly excited states—interact, one can be used to control the quantum state of the other. Two independent experiments demonstrate such 'Rydberg blockade', an effect that might make long-range quantum gates between neutral atoms possible.
