AI Article Synopsis

  • The study focuses on a hybrid system that combines a plasmonic cavity and different molecular vibration modes, offering strong optomechanical-like interactions.
  • This system serves as a quantum data bus, enabling functionalities like reciprocal and non-reciprocal information transmission between molecules.
  • It also allows for the engineering of steady-state quantum entanglement through a dissipative method, potentially broadening the applications of quantum technology beyond traditional optomechanical systems.

Article Abstract

We study a hybrid system of a plasmonic cavity coupled to a pair of different molecular vibration modes with the strong optomechanical-like interactions. Here, this plasmonic cavity is considered as a quantum data bus and then assist several applications. For instance, it can first establish a bimolecular interface to ensure the reciprocal or non-reciprocal information transmission, and then engineer both molecules into the steady-state quantum entanglement of the continuous variable through the dissipative method. In contrast to the traditional optomechanical system, this hybrid system can provide the stronger optomechanical-like interactions and more convenient controls to the molecular quantum units. This investigation is believed to be able to further expand the practical application range of quantum technology.
