The investigation of the dissipative qubit (atom) cavity system has opened up new possibilities for the development of quantum technology. Nevertheless, the understanding of this system is still poor. Also, the integration of qubit-cavity into 5G networks is still in its early stages, where the combination of 5G and quantum technology can revolutionize various sectors, including the Internet of Things IoT. Here we study a dissipative qubit-cavity quantum system, where we compute the time evolution of the excitation probabilities of the cavity and qubit as a function of the coupling strength and under the dissipation rates. To understand various processes, the study of the temperature in a cavity atom system is required. The time-evolution of the occupation probability of the cavity and qubit is achieved under different temperatures. Moreover, we examine the Wigner function at different times and under different temperatures. We demonstrate that the appearance of separation of the quantum state in WF representations depends on the coupling strength. The findings have important significance for quantum technology, including quantum information processing. Thus, we suggest an implementable schematic (network architecture based on the entangled photons) for explaining how to link cavities to a real 5G network. In this quantum route, we present a model of how time synchronization can be measured by employing quantum synchronization and integrating it into the existing 5G network.
