Conferencia; Workshop on Quantum Information; 2018

In this talk we present results on the manipulation of quantum entanglement by periodic external fieldsin the Landau-Zener-Stuckelberg interferometry of coupled flux qubits. As an entanglementmeasure we compute numerically the concurrence of two coupled flux qubits, both driven bya dc+ac magnetic flux. We show that it is possible to create or destroy entanglement in acontrolled way by tuning the system at or near multiphoton resonances.
