Effects of Dipole-Dipole Interaction and Time-Dependent Coupling on the Evolution of Entanglement and Quantum Coherence for Superconducting Qubits in a Nonlinear Field System

We examine the temporal comportment of formation entanglement and quantum coherence in a quantum system made up of two superconducting charge qubits (SC-Qs), in the case of two different classes of nonlinear field. The results discussed the impact role of time-dependent coupling (T-DC) and dipole-dipole interaction (D-DI) on the temporal comportment of quantum coherence and entanglement in the ordinary and nonlinear field. In addition, we show that the main parameters of the quantum model affect the entanglement of formation and the coherence of the system in a similar way.

Automated summary

We investigate the temporal behavior of entanglement formation and quantum coherence in a quantum system consisting of two superconducting charge qubits (SC-Qs) under two different classes of nonlinear field. The study discusses the impact of time-dependent coupling (T-DC) and dipole-dipole interaction (D-DI) on the temporal behavior of quantum coherence and entanglement in ordinary and nonlinear fields. Furthermore, it is shown that the main parameters of the quantum model affect the entanglement of formation and coherence of the system in a similar manner.
