Entanglement of Two Quantum Dots with the Flip-Flop Interaction coupled to Plasmonic Waveguide

Abstract

We investigate theoretically the entanglement of two quantum dots (QDs) coupled to metallic nanowaveguide in the presence of the flip-flop interaction with the analytical solutions of eigenvalue equations of the coupled system. High entanglement of two QDs could be achieved by adjusting the direct coupling strength of the QDs, the interaction of QDs with near-zero waveguide modes, interparticle distance of the QDs, total dissipation and detuning even when two QDs are resonant with the incident single plasmon. The discussed system with the flip-flop interaction provides us rich way to realize the quantum information processing such as quantum communication and quantum computation.
