Description
Superconducting charge qubits represent a cutting-edge technology in the field of quantum
computing. This study delves into the behaviors of thermal coherence and quantum correlations
within a two-superconducting charge qubit system coupled by a fixed capacitance. Specifically, we
investigate the effects of thermal noise on entanglement, nonclassical correlations, and quantum
coherence within the two-superconducting charge qubit capacitively coupled. Our analysis takes into
account the interplay between the equilibrium temperature of the reservoir and various system
parameters. Our findings demonstrate that an increase in temperature leads to a decrease in
coherence and quantum correlations within the considered system. However, the behavior of these
quantum resources is heavily dependent on the system parameters, and a careful selection of these
parameters can help mitigate the negative effects of absolute temperature. Additionally, we observe
that local quantum uncertainty and correlated coherence are more resilient than thermal
entanglement to rising temperatures. These results provide insight into how a two-superconducting
charge qubit system can be optimized for achieving quantum advantages.
