Abstract: An analytical theory to calculate the dissipatively stable concurrence in the system of two coupled superconducting qubits in the strong driving field is developed. The conditions for the entanglement state generation and destruction during the formation of the multiphoton transitions regions due to the interference of Landau–Zener–Stückelberg–Majorana are found. Based on the solution of the Floquet–Markov equation, the technique is proposed to adjust the amplitudes of dc- and ac-fields for effective control of the entanglement between qubit states while taking into account the effects of the decoherence.
