Molecular quantum photonics: cavity QED, cooperativity and optomechanics

SPICE Workshop on Quantum Spinoptics, June 13th - 15th 2023

Vahid Sandoghdar

Manipulation of single solid-state quantum emitters and single photons has become a routine procedure in many laboratories. Nevertheless, each emitter system (quantum dots, color centers, ions, etc.) is still confronted with a range of material constraints that pose challenges for scaling and reliable use in devices. In this presentation, I discuss our efforts of the last decade in coupling organic molecules to high-finesse Fabry-Perot open cavities and chip-based photonic circuits. We demonstrate dipole-induced transparency, strong coupling, single-photon nonlinearities as well as the cooperativity of two molecules via a common mode of a micro-resonator. Moreover, we present data on high-resolution spectroscopy of the vibronic transitions in single molecules as well as a theoretical proposal for a hybrid optomechanical platform that can lead to long coherence and storage times.
