Abstract
We demonstrate a quantum phase flip gate between two QDs that resonantly couple to plasmonic double-bar resonators with asymmetric coupling strengths. Large coupling strengths can be achieved due to the deep subwavelength mode volumes of the optical modes in plasmonic double-bar resonators. High fidelity () and high success probability of the phase gate operation have been obtained when the coupling strength ratio () and resonant mode decay rate () are optimized. The subwavelength-scale plasmonic structures provide tremendous potential for solid-state quantum information processing.
