Journal Article
Whittaker, K., Keaveney, J., Hughes, I., Sargsyan, A., Sarkisyan, D., & Adams, C. (2014). Optical Response of Gas-Phase Atoms at Less than λ/80 from a Dielectric Surface. Physical Review Letters, 112, Article 253201. https://doi.org/10.1103/physrevlett.112.253201

We present experimental observations of atom-light interactions within tens of nanometers (down to 11 nm) of a sapphire surface. Using photon counting we detect the fluorescence from of order one thousand Rb or Cs atoms, confined in a vapor with thic...

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.

All-optical quantum information processing using Rydberg gates (2014)
Journal Article
Paredes-Barato, D., & Adams, C. (2014). All-optical quantum information processing using Rydberg gates. Physical Review Letters, 112(4), Article 040501. https://doi.org/10.1103/physrevlett.112.040501

In this Letter, we propose a hybrid scheme to implement a photonic controlled-z (CZ) gate using photon storage in highly excited Rydberg states, which controls the effective photon-photon interaction using resonant microwave fields. Our scheme decoup... Read More about All-optical quantum information processing using Rydberg gates.
