Self-protected polariton states in photonic quantum metamaterials — •Matteo Biondi1, Sebastian Schmidt1, Gianni Blatter1, and Hakan E. Türeci1,2 — 1ETH Zurich, Zürich, Switzerland — 2Princeton University, Princeton, USA
We discuss the formation of polariton states in an open one-dimensional coupled cavity array containing a single qubit in its central site. Interestingly, the transmission through this quantum metamaterial exhibits two ultra-narrow resonances, corresponding to long-lived self-protected polaritonic states localized around the site containing the qubit (qubit-photon quasi-bound states). The lifetime of these states is found to increase exponentially with the number of array sites, thereby far simplifying the achievement of strong coupling in this architecture. The robustness of these states with respect to disorder is also investigated. The proposed setup is realizable with current state of the art circuit QED technology. Reference: arXiv:1309.2180
