Abstract
We examine the relationship among the fidelity, quantum coherence and Bell nonlocality in double quantum dot systems (DQDs) using transmission line resonator (TLR). We show how the physical quantities depend on the main parameters of the physical model and initial state parameter of the DQD. Moreover, we evaluate the total quantum correlation in DQDs using the skew information and display the time dependence of the quantum coherence and correlation on the main physical parameters.
