Two-qubit quantum nonlocality dynamics induced by interacting of two coupled superconducting flux qubits with a resonator under intrinsic decoherence

open access: yesAlexandria Engineering Journal, 2023
This paper explores the dynamics of two spatially separated superconducting flux qubits, initially in a maximally correlated state, without mutual interaction.

Entanglement in nonlinear two-qibit Tavis — Cummings model

open access: yesВестник Самарского университета: Естественнонаучная серия, 2023
In this work, we have studied the dynamics of entanglement of two identical superconducting qubits resonantly interacting with the one-mode field of a coplanar microwave cavity without loss through single-photon transitions in the presence of third- and ...

Dynamics of entanglement of atoms with two-photon transitions induced by a thermal field [PDF]

open access: yesКомпьютерная оптика, 2020
In this paper, we investigate the entanglement between two two-level atoms non-resonantly in-teracting with a thermal field of a lossless one-mode resonator via degenerate two-photon transi-tions.

Entanglement Research for the Coupled Superconducting Phase Qubit and a Two-Level System

open access: yesAdvances in Condensed Matter Physics, 2020
Entanglement can exist not only in the microscopic system (e.g., atom, photon, and ion trap) but also in macroscopic systems. According to recent research, entanglement can be achieved and controlled in superconducting devices.

Postponing the decay of entanglement and quantum coherence for maximally entangled mixed states under the action of correlated noise channels

open access: yesFrontiers in Quantum Science and Technology, 2023
We investigate the dynamics of a maximally entangled mixed state (MEMS) under the action of correlated noise channels. The channel acts in a way that its successive uses are correlated. We have studied the MEMS properties, including quantum coherence and

Effect of random telegraph noise on entanglement and nonlocality of a qubit-qutrit system [PDF]

open access: yesIranian Journal of Astronomy and Astrophysics, 2017
We study the evolution of entanglement and nonlocality of a non-interacting qubit-qutrit system under the effect of random telegraph noise (RTN) in independent and common environments in Markovian and non-Markovian regimes.

Dynamics of Entanglement in Jaynes–Cummings Nodes with Nonidentical Qubit-Field Coupling Strengths

open access: yesEntropy, 2017
How to analytically deal with the general entanglement dynamics of separate Jaynes–Cummings nodes with continuous-variable fields is still an open question, and few analytical approaches can be used to solve their general entanglement dynamics ...

Influence of Stark Shift on Entanglement of Two Qubits in the Two-Photon Tavis-Cummings Model

open access: yesEPJ Web of Conferences, 2015
Considering two-atom degenerate two-photon Tavis-Cummings model, we investigate the entanglement between two atoms prepared initially in the coherent disentangled states and cavity field prepared in few-photon Fock state, and study the effect of the ...
