Producing cluster states in charge qubits and flux qubits
, 2006 We propose a method to efficiently generate cluster states in charge qubits, both semiconducting and superconducting, as well as flux qubits. We show that highly-entangled cluster states can be realized by a `one-touch' entanglement operation by tuning ...

Dynamics of entanglement of separable three-qubit states in the Tavis — Cummings multiphoton model
Вестник Самарского университета: Естественнонаучная серияIn this work we study in detail the generalized Tavis — Cummings model, in which three identical qubits are trapped in a lossless single-mode resonator and interact resonantly with the quantized thermal electromagnetic field of this resonator by means of

Sudden violation of the CHSH inequality in a two qubits system
, 2010 I study the dynamics of the violation of the CHSH inequality for two qubits interacting with a common zero-temperature non-Markovian environment. I demonstrate sudden violation of the inequality for two qubits initially prepared in a factorized state ...

Journal of Mathematical Physics, 2007 The notions of entanglement witnesses and separable and entangled states for a two qubit system can be visualized in three dimensions using the SLOCC equivalence classes. This visualization preserves the duality relations between the various sets and allows us to give “proof by inspection” of a nonelementary result of Horodecki et al. [Phys. Lett.

Multipartite Entanglement and Hypergraph states of three qubits
, 2013 Several entanglement measures are used to define equivalence classes in the set of hypergraph states of three qubits. Our classifications reveal that (i) under local unitary transformations, hypergraph states of three qubits are split into six classes ...

Electronic Journal of Differential Equations, 2000 Quantum information is stored in two-level quantum systems known as qubits. The no-cloning theorem states that the state of an unknown qubit cannot be copied. This is in contrast to classical information which can be copied.

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

General solution to inhomogeneous dephasing and smooth pulse dynamical decoupling
New Journal of Physics, 2018 In order to achieve the high-fidelity quantum control needed for a broad range of quantum information technologies, reducing the effects of noise and system inhomogeneities is an essential task.
