Dynamics of entanglement of separable three-qubit states in the Tavis — Cummings multiphoton model

Вестник Самарского университета: Естественнонаучная серия
In 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

Harnessing Quantum Entanglement and Fidelity in Hydrogen Atoms: Unveiling Dynamics Under Dephasing Noise

Applied Sciences
We investigate the quantum dynamics of entanglement and fidelity in the hyperfine structure of hydrogen atoms under dephasing noise, modeled via the Lindblad master equation.

Quantum decoherence in noninertial frames

, 2010
Quantum decoherence, which appears when a system interacts with its environment in an irreversible way, plays a fundamental role in the description of quantum-to-classical transitions and has been successfully applied in some important experiments. Here,

Serendipitous ritualization: dynamics of lay connectivity in Chinese Buddhist temples and beyond Ritualisation fortuite : dynamique de la connectivité des laïques dans les temples bouddhistes chinois et au‐delà

Journal of the Royal Anthropological Institute, EarlyView.
This article contributes to rethinking the dichotomy between informal sociality and ritual formality by examining the occasional ritual encounters surrounding spirit‐tablet inscription in Chinese Buddhist temples. Rather than viewing rituals as enactments of established orders, it presents ritual engagement as a contingent process of relational ...

Decoherence and multipartite entanglement of non-inertial observers

, 2012
Decoherence effect on multipartite entanglement in non-inertial frames is investigated. GHZ state is considered to be shared between the partners with one partner in inertial frame whereas the other two in accelerated frames. One-tangle and {\pi}-tangles

Entanglement sudden-death time: a geometric quantity

, 2013
We study the entanglement evolution of the set of Bell diagonal states for a two-qubit system coupled to two independent vacuum noise sources. This set can be represented geometrically as the set of points inside a tetrahedron in a three-dimensional Euclidean space and contains the maximally entangled states for bipartite systems.

Amidst (waste) abundance: world‐making and struggles in hosting a municipal landfill in the Bolivian lowlands Au milieu de l'abondance (de déchets) : fabrication du monde et luttes liées à la gestion d'une décharge municipale dans les basses terres de Bolivie

Journal of the Royal Anthropological Institute, EarlyView.
In recent decades, solid waste has proliferated worldwide, becoming a pressing global issue. This article explores the role of Indigenous people dwelling within and upon emerging waste scenarios, with a specific focus on involved forms of sociality and ontological contestation. Drawing on the case of a municipal landfill sited on a Guarani community in

Photon Induced Entanglement in Atom-Cavity Systems

, 2010
We study the evolution of quantum entanglement in double cavity systems. The entanglement of cavity atoms induced by entangled pair of photons is investigated. Both entanglement sudden death and entanglement sudden birth phenomena are shown to be existed

Animal translations: AI and the intelligibility of non‐human worlds Traduire l'animal : l'IA et l'intelligibilité des mondes non humains

Journal of the Royal Anthropological Institute, EarlyView.
Amid the general sense of worry that large language models will soon drown out human voices, some researchers are optimistic that machine learning will allow humans to listen to and understand animal voices to an unprecedented extent. As part of a broader project aimed at interspecies communication, a loosely connected set of animal behaviourists, AI ...

Dynamics of a two-qubit Tavis-Cummings model in the presence of an Ising-type interaction between qubits

Компьютерная оптика
In this paper, we investigated the dynamics of entanglement of two qubits interacting non-resonantly with the thermal field of a one-mode lossless resonator, taking into account the Ising-type direct interaction between qubits.
