  The evolution of entanglement in a non-Hermitian quantum system may behave
differently compared to its Hermitian counterpart. In this paper, we
investigate the entanglement dynamics of two coupled and driven non-Hermitian
qubits. Through calculating the concurrence of the system, we find that the
evolution of the bipartite entanglement manifests two distinct patterns in the
parameter space. In the low non-Hermiticity regime, the concurrence oscillates
significantly, while in the opposite regime the same quantity would trend to a
stable value. We attribute this phenomenon to parity-time ($ \mathcal{PT}$)
symmetry phase transition. In addition, we have also studied the effect of
decoherence on the entanglement dynamics. Our research provides a method to
stabilize entanglement by exploiting non-Hermiticity.
