Nonviolation of the CHSH inequality under local spin-1 measurements on two spin qutrits
Louis Hanotel, Elena R. Loubenets
In the present paper, based on the general analytical expression [arXiv:2412.03470] for the maximum of the CHSH expectation under local Alice and Bob spin- measurements in a two…
High-spin measurements in an arbitrary two-qudit state
Elena R. Loubenets, Louis Hanotel
Violation of the CHSH inequality by a bipartite quantum state is now used in many quantum applications. However, the explicit analytical expression for the maximal value of the CHS…
Speed excess and total acceleration: a kinematical approach to entanglement
C. Chryssomalakos, A. G. Flores-Delgado, E. Guzmán-González +2
We show that the concept of total variance of a spin state, defined as the average of the variances of spin projection measurements along three orthogonal axes, also gives the rota…
Radiation trapping effect versus superradiance in quantum simulation of light-matter interaction
S. V. Remizov, A. A. Zhukov, W. V. Pogosov +1
We propose a realization of two remarkable effects of Dicke physics in quantum simulation of light-matter many-body interactions with artificial quantum systems. These effects are…

A. A. Zhukov, E. O. Kiktenko, A. A. Elistratov +2
We point out that realization of quantum communication protocols in programmable quantum computers provides a deep benchmark for capabilities of real quantum hardware. Particularly…
Algorithmic simulation of far-from-equilibrium dynamics using quantum computer
A. A. Zhukov, S. V. Remizov, W. V. Pogosov +1
We point out that superconducting quantum computers are prospective for the simulation of the dynamics of spin models far from equilibrium, including nonadiabatic phenomena and que…
Parametrically driven hybrid qubits-photon systems: dissipation-induced quantum entanglement and photon production from vacuum
S. V. Remizov, A. A. Zhukov, D. S. Shapiro +2
We consider a dissipative evolution of parametrically-driven qubits-cavity system under the periodical modulation of coupling energy between two subsystems, which leads to the ampl…
On the existence of a local quasi hidden variable (LqHV) model for each N-qudit state and the maximal quantum violation of Bell inequalities
Elena R. Loubenets
We specify the local quasi hidden variable (LqHV) model reproducing the probabilistic description of all N-partite joint von Neumann measurements on an N-qudit state. Via this loca…
Entanglement in a quantum neural network based on quantum dots
Mikhail V. Altaisky, Nadezhda N. Zolnikova, Natalia E. Kaputkina +3
We studied the quantum correlations between the nodes in a quantum neural network built of an array of quantum dots with dipole-dipole interaction. By means of the quasiadiabatic p…
Context-invariant and local quasi hidden variable (qHV) modelling versus contextual and nonlocal HV modelling
Elena R. Loubenets
For all the joint von Neumann measurements on a D-dimensional quantum system, we present the specific example of a context-invariant quasi hidden variable (qHV) model, proved in [L…

Mikhail V. Altaisky, Nadezhda N. Zolnikova, Natalia E. Kaputkina +3
We propose an implementation of quantum neural networks using an array of quantum dots with dipole-dipole interactions. We demonstrate that this implementation is both feasible and…

We introduce for a general correlation scenario a new simulation model, a local quasi hidden variable (LqHV) model, where locality and the measure-theoretic structure inherent to a…

We introduce a general condition sufficient for the validity of the original Bell inequality (1964) in a local hidden variable (LHV) frame. This condition can be checked experiment…
