Abstract In this work, we study qualitatively the nonclassical properties, nonlocal correlation, and geometric phase in a superconducting qubit system connected to a transmission line resonator (TLR) within a circuit quantum electrodynamics setup, where the modulation of the coupling strength can imitate the harmonic motion of the superconducting system at relativistic speeds. We analyze the effects of the relativistic motion on these quantum quantifiers under the influence of the physical parameters implicated in the whole quantum system state. Furthermore, the relationship between the different quantifiers is explored. Our results may open new perspectives to understand and explore the relativistic phenomena on the comportment of the quantum quantifiers for new applications in superconducting quantum technologies.
