摘要
Nano-optomechanical systems,capable of supporting enhanced light-matter interactions,have wide applications in studying quantum entanglement and quantum information processors.Yet,preparing optical telecomband entanglement within a single optomechanical nanobeam remains blank.We propose and design a triply resonant optomechanical nanobeam to generate steady-state entangled propagating optical modes and present its quantum-enhanced performance for teleportation-based quantum state transfer under realistic conditions.Remarkably,the entanglement quantified by logarithmic negativity can obtain E_(N)=1.Furthermore,with structural imperfections induced by realistic fabrication processes considered,the device still shows great robustness.Together with quantum interfaces between mechanical motion and solid-state qubit processors,the proposed device potentially paves the way for versatile nodes in long-distance quantum networks.
