Resumen:
The persistence of coherence of a system of superconducting flux-qubits, in presence of anensemble of electrons, is analysed. The time evolution of the system is solved exactly. We studythe time evolution of the Wigner function of the reduced density matrix of the qubits, in order todetermine the rate of decoherence induced by the coupling with the electrons. We found that therate of induced decoherence may be reduced, depending on the interactions with the electrons.Also, we discuss the squeezing properties of the system.
