Over forty years of research towards the understanding of Quantum Brownian Motion -- the contributions of A. O. Caldeira
Marcus V. S. Bonança, Sebastian Deffner, Gert-Ludwig Ingold
This article presents a brief account of Amir O. Caldeira's contributions to the theory of quantum Brownian motion. Motivated by its importance, we outline the description of Brown…
FALQON-MST: A Fully Quantum Framework for Graph Optimization in Vision Systems
Guilherme E. L. Pexe, Lucas A. M. Rattighieri, Leandro A. Passos +4
Finding the minimum spanning tree (MST) of a graph is an important task in computer vision, as it enables a sparse and low-cost representation of connectivity among elements (such…
An introductory review of the theory of continuous-variable quantum key distribution: Fundamentals, protocols, and security
Maron F Anka, John A. Mora Rodríguez, Douglas F. Pinto +3
Continuous-variable quantum key distribution (CV-QKD) has emerged as a promising approach for secure quantum communication, offering advantages such as high key generation rates, c…
Absorption-based qubit estimation in discrete-time quantum walks
Edgard P. M. Amorim, Lorena R. Cerutti, O. P. de Sá Neto +1
We investigate state estimation in discrete-time quantum walks with a single absorbing boundary. Using a spectral approach, we obtain closed expressions for the escape probability…

We investigate the formulation of work distributions for quantum scalar fields in static curved spacetimes by extending the Ramsey interferometric protocol originally developed in…
Can outcome communication explain Bell nonlocality?
Carlos Vieira, Carlos de Gois, Pedro Lauand +3
A central aspect of quantum information is that correlations between spacelike separated observers sharing entangled states cannot be reproduced by local hidden variable (LHV) mode…

Italo L. Soares Andrade, Kleber Pirota, Amir O. Caldeira +1
We report the observation of the Purcell effect in a cavity-metallic magnet hybrid system using electric-field-mediated coupling. In this configuration, microwave-induced axial cur…
Revisiting the Jaynes-Cummings model with time-dependent coupling
Thiago T. Tsutsui, Danilo Cius, Antonio Vidiella-Barranco +2
The Jaynes-Cummings (JC) model stands as a fully quantized, fundamental framework for exploring light-matter interactions, a timely reflection on a century of quantum theory. The t…
Entanglement swapping for partially entangled qudits and the role of quantum complementarity
Diego S. Starke, Marcos L. W. Basso, Lucas C. Céleri +1
We extend the entanglement swapping protocol (ESP) to partially entangled qudit states and analyze the process within the framework of complete complementarity relations (CCRs). Bu…
