Title: Tuning light-matter interfaces for scalable quantum information processing platforms

Abstract: The milestones achieved in quantum information processing (QIP) have been driven by the realization of qubit modalities in a variety of physical systems (trapped ions, superconducting circuits, photons, electron and nuclear spins ...).  Given the complementary advantages of these different qubit implementations, integrating different systems in hybrid systems is increasingly perceived as the viable path towards scalability. To this end, optimal interfaces between disparate systems are essential. In this talk, we will discuss challenges that arise at these interfaces and some efforts that are being undertaken to address them. In particular, we will discuss remedies that we are pursuing to supplement device manufacturing/engineering by applying suitable control protocols on disparate quantum emitters to improve their performance in various photon-mediated operations in QIP. 

Bio: Dr. Fotso holds a PhD from Louisiana State University (LSU). After a postdoctoral fellowship at Georgetown University followed by another one at the DOE Ames Laboratory in Ames, Iowa, he became an assistant professor at the University at Albany SUNY before moving to his current position with the Department of Physics at the University at Buffalo SUNY. In his research, Dr Fotso studies the nonequilibrium dynamics of many-particle quantum systems. He is particularly interested on the one hand, in nonequilibrium quantum materials and, on the other hand, in light-matter interfaces that are pertinent for Quantum Information Processing.
