• Abstract summary: We propose an optical single-photon switch based on Rydberg atoms that interact through van der Waals interactions. A weak coherent field probes the atomic cloud continuously, and when a single photon excites a Rydberg state, it breaks the conditions for electromagnetically induced transparency. The proposed device extends the toolkit for quantum light manipulation and photon readout, and represents a continuous wave version of previously demonstrated single-photon transistors.

• Abstract: We propose an optical single-photon switch based on Rydberg atoms that interact through van der Waals interactions. A weak coherent field probes the atomic cloud continuously, and when a single photon excites a Rydberg state, it breaks the conditions for electromagnetically induced transparency, altering the reflection/transmission. Two versions of the device are proposed, one in a single-sided cavity and the other in free space. The proposed device extends the toolkit for quantum light manipulation and photon readout, and represents a continuous wave version of previously demonstrated single-photon transistors.

  We show that in the inelastic collision of a photon and an atom, the twisted state of the photon is transferred to the center-of-mass state. We also show that, depending on the experimental conditions, the twistedness of the photon is either transferred to the atomic center-of-mass quantum state or modifies the selection rule for the bound electron transition.

For three photons, the formation of vortex lines and a central vortex ring attests to a genuine three-photon interaction.

  Enhancing light-matter coupling at the level of single quanta is essential for numerous applications in quantum science. Cooperative optical response of subwavelength atomic arrays has been found to open new pathways for such strong light-matter couplings. We demonstrate spatial control over the optical response of an atomically thin mirror formed by a subwavelength array of atoms in free space.

  We investigate the interaction of weak light fields with two-dimensional lattices of atoms, in which two-photon coupling establishes conditions of electromagnetically induced transparency and excites high lying atomic Rydberg states. Such strong photon-photon interactions in the absence of otherwise detrimental photon losses in Rydberg-EIT arrays opens up a promising approach for the generation and manipulation of quantum light, and the exploration of many-body phenomena with interacting photons.

The resulting Floquet polaritons involve a superposition of a set of cavity modes with a density of excitation of the atomic cloud.

  Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols. Here, we demonstrate a functional source of high-dimensional, noise-resilient hyperentangled states encoded in time-frequency and vector-vortex structured modes. We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
