  In this work, we study the coupling between a superconducting device as a dc
SQUID, simulated from an artificial atom with two degrees of freedom, and a
single-mode radiation field for the information transference process. We
demonstrate that the population transfer among the energy levels of the
artificial atom yields an entanglement dynamics, which leads to the generation
of a pair of photons. Moreover, we show the quantum information transference
between the internal modes of the superconducting device, initially in a
maximally entangled state, and the radiation field. The artificial atom absorbs
the photon, and the radiation field modes become entangled as quantum coherence
is transmitted from the superconducting device to the photons. These results
strengthen the applicability of superconducting devices for the transference of
quantum information, contributing to promising applications in emerging quantum
technologies.
