How Negative Is Negative Information [PDF]

open access: yesFrontiers in Neuroscience, 2021
Daily, we face a plenty of negative information that can profoundly affect our perception and behavior. During devastating events such as the current COVID-19 pandemic, negative messages may hinder reasoning at individual level and social decisions in the society at large.

Switching and Swapping of Quantum Information: Entropy and Entanglement Level

open access: yesEntropy, 2021
Information switching and swapping seem to be fundamental elements of quantum communication protocols. Another crucial issue is the presence of entanglement and its level in inspected quantum systems. In this article, a formal definition of the operation

Influence of detuning and Kerr nonlinearity on atom-atom entanglement in the double two-photon Jaynes–Cummings model

open access: yesФизика волновых процессов и радиотехнические системы, 2021
In this work, the authors investigated the dynamics of entanglement of two identical two-level atoms (qubits) in the framework of the two-photon double Jaynes–Cummings model, taking into account the detuning between atoms and the double frequency of the ...

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 ...

Entanglemnt in nonlinear three-qubits Jaynes — Cummings

open access: yesВестник Самарского университета: Естественнонаучная серия, 2023
In this paper, we investigated the dynamics of entanglement of pairs of qubits in a system of three identical qubits that interact non-resonantly with the selected mode of a microwave resonator without loss with the Kerr medium by means of single-photon ...

Hegel's Absolute as Negativity [PDF]

open access: yesJournal of Philosophical Investigations, 2021
The relation of the many and the one, difference and identity, multiplicity and unity, particularity and universality, and finally that of negativity and negativity of negativity through reason and history is the core of Hegelian Absolute which is still ...

Entanglement of atoms induced by thermal noise in the presence of initial atomic coherence

open access: yesФизика волновых процессов и радиотехнические системы, 2020
In this article, author investigated the dynamics of entanglement of two dipole-coupled natural or artificial two-level atoms (qubits) interacting nonresonantly with the intensive one-mode cavity thermal field.

Priming Partisan Identities and Support for Political Violence

open access: yesFrontiers in Political Science, 2022
Individuals in the United States appear increasingly willing to support and justify political violence. This paper therefore examines whether making partisan identities salient increases support for political violence. We embed priming manipulations in a

Quantumness Measures for a System of Two Qubits Interacting with a Field in the Presence of the Time-Dependent Interaction and Kerr Medium

open access: yesEntropy, 2021
In this work, we introduce the standard Tavis-Cummings model to describe two-qubit system interacting with a single-mode field associated to power-law (PL) potentials. We explore the effect of the time-dependent interaction and the Kerr-like medium.

Negativity Bounds for Weyl-Heisenberg Quasiprobability Representations [PDF]

open access: yes, 2017
The appearance of negative terms in quasiprobability representations of quantum theory is known to be inevitable, and, due to its equivalence with the onset of contextuality, of central interest in quantum computation and information.
