  In this work we report on a new mechanism to generate dissipative steady
state entanglement in two coupled qubits driven by strong periodic ac fields.
We show that steady entanglement can be generated at one side of a multiphoton
resonance between a non-entangled ground state and an entangled excited state.
The degree of entanglement can be tuned as a function of the amplitude of the
periodic drive. A rich dynamic behavior with creation, death and revival of
entanglement can be observed for certain parameter regimes, accessible in
current experimental devices.
