Journal Article
Busche, H., Huillery, P., Ball, S. W., Ilieva, T., Jones, M. P., & Adams, C. S. (2017). Contactless nonlinear optics mediated by long-range Rydberg interactions. Nature Physics, 13(7), 655-658. https://doi.org/10.1038/nphys4058

In conventional nonlinear optics, linear quantum optics1, 2, and cavity quantum electrodynamics3, 4 to create effective photon–photon interactions photons must have, at one time, interacted with matter inside a common medium. In contrast, in Rydberg... Read More about Contactless nonlinear optics mediated by long-range Rydberg interactions.

A high repetition rate experimental setup for quantum non-linear optics with cold Rydberg atoms (2016)
Journal Article
Busche, H., Ball, S. W., & Huillery, P. (2016). A high repetition rate experimental setup for quantum non-linear optics with cold Rydberg atoms. European Physical Journal - Special Topics, 225(15), 2839-2861. https://doi.org/10.1140/epjst/e2015-50338-3

Using electromagnetically induced transparency and photon storage, the strong dipolar interactions between Rydberg atoms and the resulting dipole blockade can be mapped onto light fields to realise optical non-linearities and interactions at the sing...

Microwave control of the interaction between two optical photons (2014)
Journal Article
Maxwell, D., Szwer, D., Barato, D., Busche, H., Pritchard, J., Gauguet, A., …Adams, C. (2014). Microwave control of the interaction between two optical photons. Physical Review A, 89(4), Article 043827. https://doi.org/10.1103/physreva.89.043827

A microwave field is used to control the interaction between pairs of optical photons stored in highly excited collective states (Rydberg polaritons). We show that strong dipole-dipole interactions induced by the microwave field destroy the coherence... Read More about Microwave control of the interaction between two optical photons.

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...
