Entanglement dynamics of a dc SQUID interacting with a single mode radiation field

In this work, we study the entanglement dynamics in the coupling between a superconducting device as a dc SQUID and a single-mode radiation field for the information transference process. We show that a pair of photons can be generated through the entanglement dynamics which emerge from the atomic population transfer. In this regard, we also demonstrate the transfer of entanglement and quantum coherence from the superconducting device to the radiation field modes, where entanglement is transferred as the quantum coherence is transmitted, since both stem from the quantum superposition principle, encapsulating the quantumness of the system.
