We investigate the indistinguishability of single photons retrieved from collective Rydberg excitations in cold atomic ensembles. The Rydberg spin waves are created either by off-resonant two-photon excitation to the Rydberg state or by Rydberg elect

The state of a single photon can be stored as a Rydberg excitation using electromagnetically induced transparency, and this enables nonlinear interactions at the single-photon level. Here, the authors store a paired photon emitted by a quantum memory

We study the photon statistics of weak coherent pulses propagating through a cold atomic ensemble in the regime of Rydberg electromagnetically induced transparency. We show experimentally that the value of the second-order autocorrelation function of

Generation of narrowband pure and storable single photons is an enabling step towards hybrid quantum networks interconnecting different systems. Here the authors report on a heralded single photon source based on a cold ensemble of atoms with control

One of the biggest challenges in experimental quantum information is to sustain the fragile superposition state of a qubit1. Long lifetimes can be achieved for material qubit carriers as memories2, at least in principle, but not for propagating photo

Future quantum repeater architectures, capable of efficiently distributing information encoded in quantum states of light over large distances, rely on quantum memories for light [1]. Quantum repeaters can benefit from a modal multiplexing implementa

Photons are very good candidates to carry quantum information due to their negligible interactions. However, photon-photon interactions are needed to process photonic quantum information. This is very useful for quantum repeater applications [1], in

We demonstrate a medium with single-photon non-linearity based on cold Rydberg atoms, suitable for the mapping of a paired single photon. This opens the door to quantum interactions between single photons.
