    Area of Science:

    • Quantum physics
    • Optomechanics
    • Quantum information science

    Background:

    • Cavity optomechanical systems (COMSs) are crucial for quantum information processing.
    • Generating entanglement between remote quantum systems is a key challenge.

    Purpose of the Study:

    • To propose a novel scheme for generating entanglement between two COMSs.
    • To analyze the mechanisms and feasibility of this entanglement generation.

    Main Methods:

    • Derivation of analytical expressions for entangled states.
    • Analysis of entanglement transfer and swapping processes.
    • Investigation of decoherence effects and experimental feasibility.

    Main Results:

    • Successfully derived analytical expressions for entangled states between two COMSs.
    • Identified two distinct entanglement generation processes: entanglement transfer and entanglement swapping-like phenomena.
    • Analyzed the influence of inter-system distance on entanglement.

    Conclusions:

    • The proposed scheme effectively generates entanglement between two COMSs via a flying atom.
    • The study provides a comprehensive analysis of entanglement dynamics, decoherence, and experimental viability.
