A Rydberg spin wave is optically excited in a quasi-one-dimensional atomic sample of Rb atoms. Emergence of long-range correlations of collective atomic excitations due to long-range Rydberg interactions is observed by spatially selective conversion of the spin wave into a light field and photoelectric correlation measurements of the light.
