Abstract

We demonstrate efficient processes of entanglement generation and quantum state transfer (QST) with dipole emitters coupled to a plasmonic double-bar resonator. The bipartite and multipartite maximal entanglement and complete QST can be deterministically achieved by selecting appropriate coupling strength between individual emitters and the resonator mode. Moreover, the entanglement dynamics show that high fidelities of entanglement generation and QST can be realized even under imprecise coupling strength and the system decay. The feasibility analysis and practical implementation are discussed, which manifest that our schemes may be meaningful for exploring solid-state quantum information processing with the metal plasmonic mode.
