Quantum Information Processing in the Ultrastrong Coupling Regime
Dr. Guillermo Romero, Assistant Professor
University of Santiago of Chile

In recent years we have witnessed an impressive development in the field of circuit quantum electrodynamics (QED), which has reached the level of control of trapped ions technology. A landmark in circuit QED is the ultrastrong coupling regime of light-matter interaction where the coupling strength is comparable to the resonator frequency. A natural question is whether we can benefit from this coupling regime for the sake of quantum information tasks. This talk will present some contributions regarding this matter. In particular, I will show the performance of ultrafast quantum gates, quantum memory based on parity protected two-level systems, and the engineering of polariton states.
