Nanophotonics for Quantum Information & Simulation
Co-authors: Carlos Sánchez-Muñoz, Carlos Tejedor, Fabrice Laussy

Nanophotonics is believed to play a central role in future quantum technologies [1]. Thus, the ability to engineer, create and detect light exploiting its quantum attributes appears as one of the main theoretical and technological challenges in the forthcoming years. Both metals and semiconductor are promising implementations for manipulating light at the nanoscale. The existence of surface plasmon polaritons in metal-dielectric interfaces allows for deep subwavelength confinement, whereas the possibility to engineer photonic bandgaps in semiconductor materials can be used to mold the flow of light confining it to effective one and 0-dimensional systems. In this presentation, I will show how to exploit these systems to mediate interactions between quantum emitters in both one and two-dimensional geometries that lead to entanglement generation [2] and analyze the emergence of strong-coupling in the case of metal-dielectric interfaces [3]. Moreover, I will explain how the study of frequency filtered correlations can be used to engineer and unravel complex quantum dynamics in these systems [4].

Gaël Nardin

University of Colorado & NIST
Gael Nardin completed his PhD thesis at EPFL, at the Laboratory of Quantum Optoelectronics. He developed and used time-resolved interferometric imaging techniques to study the dynamics of exciton polaritons in semiconductor microcavities. He is now a post-doctoral research associate at JILA, implementing a novel concept of coherent multi-dimensional spectroscopy to study low-dimensional semiconductor nanostructures.
