摘要：

We conduct a study into the impact of frequency modulation on the dynamic behavior of qubit-photon entanglement inside a leaky cavity and subsequently on the entanglement swapping between such two qubits. Furthermore, we investigate how frequency modulation can affect the entropic uncertainty and its lower bound. It is revealed that there are optimal modulation parameters for which the system experiences a long-lasting qubit-photon entanglement as well as a robust swapped entanglement. Moreover, the obtained result indicates that for the optimal modulation parameters, the entropic uncertainty can be maintained small for a long time.
