Excitation spectrum of a multilevel atom coupled with a dielectric nanostructure
N. A. Moroz, L. V. Gerasimov, A. D. Manukhova +1
We develop a microscopic calculation scheme for the excitation spectrum of a single-electron atom localized near a dielectric nanostructure. The atom originally has an arbitrary de…
Error mitigated variational algorithm on a photonic processor
O. V. Borzenkova, G. I. Struchalin, I. Kondratyev +3
Our study demonstrates successful error mitigation of indistinguishability-related noise in a quantum photonic processor through the application of the zero-noise extrapolation tec…
Speeding up qubit control with bipolar single-flux-quantum pulse sequences
Vsevolod Vozhakov, Marina Bastrakova, Nikolay Klenov +2
The development of quantum computers based on superconductors requires the improvement of the qubit state control approach aimed at the increase of the hardware energy efficiency.…
Probing quantum chaos with the entropy of decoherent histories
Evgeny Polyakov, Nataliya Arefyeva
Quantum chaos, a phenomenon that began to be studied in the last century, still does not have a rigorous understanding. By virtue of the correspondence principle, the properties of…
Entanglement and quantum discord in the cavity QED models
Hui-hui Miao, Wanshun Li
We investigate the quantum correlation between light and matter in bipartite quantum systems, drawing on the Jaynes-Cummings model and the Tavis-Cummings model, which are well-esta…
On time-dependent projectors and on generalization of thermodynamical approach to open quantum systems
K. Sh. Meretukov, A. E. Teretenkov
In this paper, we develop a consistent perturbative technique for obtaining a time-local master equation based on projective methods in the case where the projector depends on time…
Benchmarking a boson sampler with Hamming nets
Ilia A. Iakovlev, Oleg M. Sotnikov, Ivan V. Dyakonov +4
Analyzing the properties of complex quantum systems is crucial for further development of quantum devices, yet this task is typically challenging and demanding with respect to requ…
Enhanced optomechanical interaction in the unbalanced interferometer
Alexandr Karpenko, Mikhail Korobko, Sergey P. Vyatchanin
Quantum optomechanical systems enable the study of fundamental questions on quantum nature of massive objects. For that a strong coupling between light and mechanical motion is req…
Description of the non-Markovian dynamics of atoms in terms of a pure state
Yuri Ozhigov, You Jiangchuan
The quantum master equation (QME), used to describe the Markov process of interaction between atoms and field, has a number of significant drawbacks. It is extremely memory intensi…
Resonant generation of high-order harmonics in nonlinear electrodynamics
Ilia Kopchinskii, Petr Satunin
We study the process of resonant generation of high-order harmonics in a closed cavity in the model of vacuum nonlinear electrodynamics. Concretely, we study the possibility of res…
Time-convolutionless master equations for composite open quantum systems
A. Yu. Karasev, A. E. Teretenkov
In this work we consider the master equations for composite open quantum systems. We provide purely algebraic formulae for terms of perturbation series defining such equations. We…
Comparing the effects of nuclear and electron spins on the formation of neutral hydrogen molecule
Hui-hui Miao, Yuri Igorevich Ozhigov
We introduce the association-dissociation model of neutral hydrogen molecule, which is a finite-dimensional cavity quantum electrodynamics model of chemistry with two two-level art…
