PIEAS-QTeQ paper published in PRA

QTeQ former long-term visitor Fazal Badshah has published a paper on the dynamics of a coupled-cavity array containing multiple two-level atoms. The work, written in collaboration with Prof. Shahid Qamar (PIEAS, Islamabad) and Mauro describes the generation of multisite entangled states and the transfer of excitations resulting from the competition of tunnelling and onsite nonlinearities.

The paper is the result of the great work that Fazal did in Belfast in 2013, supported by a HEC studentship from Pakistan and the generosity of Shahid. At QTeQ we all wish to see Fazal soon and to keep up the collaboration with him and Shahid.
