the FET Work Programme 2016-2017 - FETFLAG-02-2017: Coordination and Support Action for Quantum Technologies


The 2016-2017 FET programme has been updated in order to include a new call for a coordination action for Quantum Technologies

the FET Work Programme 2016-2017 has been adopted yesterday and is now available here: http://ec.europa.eu/research/participants/data/ref/h2020/wp/2016_2017/main/h2020-wp1617-fet_en.pdf

As you will see on page 36, there is an additional call FETFLAG-02-2017: Coordination and Support Action for Quantum Technologies

The call will open on 23 May 2017 and close on 26 September 2017.

Rydberg-induced optical nonlinearities from a cold atomic ensemble trapped inside a cavity

We experimentally characterize the optical nonlinear response of a cold atomic medium placed inside an optical cavity, and excited to Rydberg states. The excitation to S and D Rydberg levels is carried out via a two-photon transition in an electromagnetically induced transparency configuration, with a weak (red) probe beam on the lower transition, and a strong (blue) coupling beam on the upper transition. The observed optical nonlinearities induced by S states for the probe beam can be explained using a semi-classical model with van der Waals' interactions.

Inelastic Photon Scattering via the Intracavity Rydberg Blockade


A. Grankin, E. Brion, R. Boddeda, S. Ćuk, I. Usmani, A. Ourjoumtsev & P. Grangier


Phys. Rev. Lett. 117, 253602 (2016)

Electromagnetically induced transparency (EIT) in a ladder system involving a Rydberg level is known to yield giant optical nonlinearities for the probe field, even in the few-photon regime. This enhancement is due to the strong dipole-dipole interactions between Rydberg atoms and the resulting excitation blockade phenomenon. In order to study such highly correlated media, ad hoc models or low-excitation assumptions are generally used to tackle their dynamical response to optical fields.
