We study the dynamics of tripartite entanglement in a system of two strongly driven qubits individually coupled to a dissipative cavity. We aim to explain the previously noted entanglement revival between two qubits in this system. We show that the periods of entanglement loss correspond to the tripartite entanglement formation between the qubits and the cavity, and the recovery is associated with an inverse process. We demonstrate that the overall process of qubit–qubit entanglement loss is due to the coupling to the cavity, and further loss of multipartite entanglement is due to the coupling of the cavity to the external continuum, which explains the behaviour of the qubit–qubit entanglement loss reported previously.
