Two superconducting (SC) qubits interacting with a radiation field in the coherent state (CS) in the presence of Stark shift are investigated. The density matrix is expressed in terms of the wave function to describe the proposed system. Physical properties, such as the geometric phase, linear entropy, and negativity are used to describe the behavior of the system. The effects of the Stark shift and the initial state on the linear entropy, geometric phase, and nonclassical correlation are discussed. Thermal and magnetic field interactions are also examined during the time evolution of the two SC qubits. By raising the temperature and decreasing the qubit–qubit entanglement, the nonclassical connection between the CS field and the two SC qubits is strengthened. Moreover, the Stark shift considerably affects the dynamical and physical properties of both types of entanglement.

斯塔克频移对耦合相干辐射场的两个超导量子位系统的影响

研究了在存在斯塔克频移的情况下与相干态（CS）中的辐射场相互作用的两个超导（SC）量子位。密度矩阵用波函数表示，以描述所提出的系统。物理属性（例如几何相位，线性熵和负性）用于描述系统的行为。讨论了Stark位移和初始状态对线性熵，几何相位和非经典相关性的影响。在两个SC量子位的时间演化过程中，还检查了热和磁场的相互作用。通过提高温度并减少量子位-量子位纠缠，可以增强CS场和两个SC量子位之间的非经典联系。此外，
