Plasmon mediated quantum communication between quantum dot clouds

ORAL

Abstract

We report experimental and theoretical studies of the interaction of a quantum dot (QD) cloud [1] with a remote QD cloud mediated by surface lattice resonances (SLR) in two dimensional array of plasmonic nanoparticles[2]. By exciting one QD cloud and collecting the photoluminescence from a remote, unexcited QD cloud, we experimentally demonstrate long range, SLR mediated coupling between the two clouds. We explore the coupling between the two QD clouds through the SLR. Our results suggest an exciting new direction where coherent plasmonic systems can mediate interactions between remote QDs, having various applications in quantum information processing and quantum computation, such as realizing two qubit gate interactions between the QD clouds.
