Вестник Самарского университета: Естественнонаучная серияThe article studies the dynamics of pairwise entanglement of three qubits, two of which are trapped in a resonator and interact with a single-mode ideal resonator through single-photon transitions, and the third qubit is outside the resonator. This takes

Entanglement of A Qubit‐Qutrit System: Impact of Ohmic Noise
Advanced Physics ResearchThis research examines the dynamics of quantum correlations in a hybrid qubit–qutrit system subjected to an Ohmic noisy environment. While entanglement degradation in homogeneous systems is well‐documented, the behavior of disparate‐dimensional ...

DYNAMICS AND ENTANGLEMENT OF A QUANTUM DOT-CAVITY SYSTEM COUPLED BY A NON-LINEAR OPTICAL INTERACTION
Momento, 2017 We propose a simple theoretical model for a dissipative quantum dot-microcavity system interacting with a non-linear optical interaction. The Lindblad master equation formalism is considered to study the full dynamics for both weak and strong coupling ...

Вестник Самарского университета: Естественнонаучная серияIn this paper, we study the dynamics of a system consisting of two identical qubits interacting non-resonantly with a single-mode field of an ideal resonator in the presence of direct dipole-dipole and Ising interactions between the qubits.

Symmetry in the open-system dynamics of quantum correlations
Scientific Reports, 2017 We study the symmetry properties in the dynamics of quantum correlations for two-qubit systems in one-sided noisy channels, with respect to a switch in the location of noise from one qubit to the other.

Dynamics of atom-atom entanglement in two-atom model with degenerate two-photon raman transitions
Вестник Самарского университета: Естественнонаучная серияThe exact dynamics of a model consisting of two two-level atoms interacting with the electromagnetic field mode of an ideal resonator through degenerate Raman transitions are found for coherent and thermal field states.

Dynamics of qubit entanglement in three-qubit Jaynes–Cummings model for biseparable intial states
Физика волновых процессов и радиотехнические системыBackground. To operate a quantum computer, a set of universal gates must be implemented, such as a two-cubit gate of the controlled negation type plus one-cubit spins. As a universal alternative, three-cubic-bit gates may be used.

Quantumness of hybrid systems under quantum noise
Scientific ReportsWe investigate the quantum correlations in an axially symmetric hybrid qubit–qutrit system subjected to different noisy environments. We first introduce a physical model and analyze its Hamiltonian structure, emphasizing the role of hybrid dimensionality
