As shown in the figure, two atoms trapped in an optical cavity are connected by an optical fiber with a strength of η. In addition, the two atoms have the same three-level structure, two ground states |0⟩, |1⟩, and one excited state |2⟩ corresponding to energies ω₀, ω₁, and ω₂ respectively, and the energy levels |0⟩ and |2⟩ of atom 1 (2) are coupled by adding laser Ω_{1 (2)}(t), and the energy levels |1⟩ and |2⟩ are coupled by cavity, and the coupling strength is g₁₍₂₎. Here, the detuning between energy levels |1⟩ and |2⟩ is equal to 0.
