Dynamics for two cavity QED systems coupled by an optical fiber

We discuss the one-excitation dynamics of two atomic qubits, trapped in separate cavities coupled through a short optical fiber. Our investigation shows that a wide variety of time-evolution behaviors can be realized by modulating the atom–cavity detuning δ, the atom–cavity coupling strength g and the cavity–fiber hopping strength v. ► We model two Cavity QED systems coupled by an optical fiber which can be used to realize the distributed quantum computation. ► We discuss the one-excitation dynamics of the system at any given atom-cavity detuning. ► A wide variety of time-evolution behaviors can be realized by modulating the atom-cavity coupling strength and the cavity-fiber hopping strength.
