An analytical solution for the dissipative system of two charge qubits located in an SC-cavity field is obtained in the dispersive regime. Therefore, the quantum correlation of the trace distance discord, the Bell function and the logarithmic negativity are investigated. The sensitivity of the correlation measures are investigated under the physical parameters of the phase damping and the qubit distribution angle of the initial symmetric/non-symmetric Bell-state, whereby correlation phenomena, such as the oscillatory behavior, disappearance/appearance and the collapses/revivals, are proven to demonstrate noticeable changes and high sensitivity to these physical parameters. It is shown that the unitary cavity-qubit interaction leads to the generation of quantum correlations periodically with different amplitudes and oscillations which depend on the initial two-qubit state and its distribution angle. The increase of the two-qubit phase damping leads to the complete disappearance of the generated trace distance, Bell function and log-negativity correlations.

在与耗散 SC 腔相互作用的两个 SC 量子位中，追踪距离不一致和贝尔函数相关性超出纠缠

在色散状态下获得了位于 SC 腔场中的两个电荷量子位的耗散系统的解析解。因此，研究了迹距不协调、贝尔函数和对数负性的量子相关性。在初始对称/非对称贝尔态的相位阻尼和量子位分布角的物理参数下研究相关度量的灵敏度，由此相关现象，如振荡行为、消失/出现和崩溃/复兴，被证明表现出明显的变化和对这些物理参数的高度敏感性。结果表明，幺正腔-量子位相互作用导致周期性地产生具有不同幅度和振荡的量子关联，这取决于初始的双量子位状态及其分布角。双量子位相位阻尼的增加导致生成的轨迹距离、贝尔函数和对数负相关性完全消失。
