Plasmon-mediated strong coupling between spatially separated and thus selectively addressable quantum emitters is a worthwhile goal for conveying quantum optical many-body interactions to ultrafast timescales. For this purpose we employ a recently demonstrated hybridization scheme [1] that combines the longevity and waveguide character of an elliptical plasmon cavity with the strong field enhancement of nanoantennas positioned in the associated focal spots. Quantum dynamical simulations reveal an oscillatory exchange of excited state population and a notable degree of entanglement between the attached quantum emitters over a distance of 1.8 µm [2].
Presently, we study coherent control and time-resolved spectroscopy of quantum emitter-related nonclassical photon correlations in this device and show first results.
