The implementation of electromagnetically induced transparency (EIT) in a cold Rydberg gas provides an attractive route towards strong photon–photon interactions and fully deterministic all-optical quantum information processing. In this brief review... Read More about Nonlinear optics using cold Rydberg atoms.

Optical coherences and wavelength mismatch in ladder systems (2013)
Journal Article
Urvoy, A., Carr, C., Ritter, R., Adams, C., Weatherill, K., & Löw, R. (2013). Optical coherences and wavelength mismatch in ladder systems. Journal of Physics B: Atomic, Molecular and Optical Physics, 46(24), Article 245001. https://doi.org/10.1088/0953-4075/46/24/245001

We investigate experimentally and theoretically the coherent and incoherent processes in open three-level ladder systems in room temperature gases and identify in which regime electromagnetically induced transparency (EIT) occurs. The peculiarity of... Read More about Optical coherences and wavelength mismatch in ladder systems.

Fast and quasideterministic single ion source from a dipole-blockaded atomic ensemble (2013)
Journal Article
Ates, C., Lesanovsky, I., Adams, C., & Weatherill, K. (2013). Fast and quasideterministic single ion source from a dipole-blockaded atomic ensemble. Physical Review Letters, 110(21), Article 213003. https://doi.org/10.1103/physrevlett.110.213003

We present a fast and quasideterministic protocol for the production of single ions and electrons from a cloud of laser-cooled atoms. The approach is based on a two-step process where first a single Rydberg atom is photoexcited from a dipole-blockade...

Storage and Control of Optical Photons Using Rydberg Polaritons (2013)
Journal Article
Maxwell, D., Szwer, D., Paredes-Barato, D., Busche, H., Pritchard, J., Gauguet, A., …Adams, C. (2013). Storage and Control of Optical Photons Using Rydberg Polaritons. Physical Review Letters, 110(10), Article 103001. https://doi.org/10.1103/physrevlett.110.103001

We use a microwave field to control the quantum state of optical photons stored in a cold atomic cloud. The photons are stored in highly excited collective states (Rydberg polaritons) enabling both fast qubit rotations and control of photon-photon in...

Nonequilibrium phase transition in a dilute Rydberg Ensemble (2013)
Journal Article
Carr, C., Ritter, R., Wade, C., Adams, C., & Weatherill, K. (2013). Nonequilibrium phase transition in a dilute Rydberg Ensemble. Physical Review Letters, 111(11), Article 113901. https://doi.org/10.1103/physrevlett.111.113901

We demonstrate a nonequilibrium phase transition in a dilute thermal atomic gas. The phase transition, between states of low and high Rydberg occupancy, is induced by resonant dipole-dipole interactions between Rydberg atoms. The gas can be considere...
