Amplitude tuning of steady-state entanglement in strongly driven coupled qubits

Abstract

We report a mechanism to generate dissipative steady-state entanglement in coupled solid-state qubits driven by strong periodic fields. We demonstrate that steady entanglement can be induced and tuned by changing the amplitude of the driving field. A rich dynamic behavior with creation, death, and revival of entanglement can be observed near multiphoton resonances. Coupled superconducting qubits are good candidates for the observation of these effects.
