A portrait of the collaboration network in quantum information
Samuraí Brito, Rute Oliveira, Raabe Oliveira +1
From its inception at the beginning of the eighties, with milestone results and ideas such as quantum simulation, the no-cloning theorem, and quantum computers, quantum information…
Statistical mechanical approach of complex networks with weighted links
Rute Oliveira, Samuraí Brito, Luciano R. da Silva +1
Systems which consist of many localized constituents interacting with each other can be represented by complex networks. Consistently, network science has become highly popular in…
Quantum communication complexity beyond Bell nonlocality
Joseph Ho, George Moreno, Samuraí Brito +8
Efficient distributed computing offers a scalable strategy for solving resource-demanding tasks such as parallel computation and circuit optimisation. Crucially, the communication…
General Method for Classicality Certification in the Prepare and Measure Scenario
Carlos de Gois, George Moreno, Ranieri Nery +3
Preparation and measurement of physical systems are the operational building blocks of any physical experiment, and to describe them is the first purpose of any physical theory. It…
Connecting complex networks to nonadditive entropies
R. M. de Oliveira, Samuraí Brito, L. R. da Silva +1
Boltzmann-Gibbs statistical mechanics applies satisfactorily to a plethora of systems. It fails however for complex systems generically involving strong space-time entanglement. It…
Satellite-based photonic quantum networks are small-world
Samuraí Brito, Askery Canabarro, Daniel Cavalcanti +1
Recent milestone experiments establishing satellite-to-ground quantum communication are paving the way for the development of the quantum internet, a network interconnected by quan…
Bell non-locality using tensor networks and sparse recovery
I. S. Eliëns, S. G. A. Brito, R. Chaves
Bell's theorem, stating that quantum predictions are incompatible with a local hidden variable description, is a cornerstone of quantum theory and at the center of many quantum inf…
Statistical properties of the quantum internet
Samuraí Brito, Askery Canabarro, Rafael Chaves +1
Steady technological advances are paving the way for the implementation of the quantum internet, a network of locations interconnected by quantum channels. Here we propose a model…
Device-Independent Secret Sharing and a Stronger Form of Bell Nonlocality
M. G. M. Moreno, Samuraí Brito, Ranieri V. Nery +1
Bell nonlocality, the fact that local hidden variable models cannot reproduce the correlations obtained by measurements on entangled states, is a cornerstone in our modern understa…
Nonlocality Distillation and Quantum Voids
S. G. A. Brito, M. G. M. Moreno, A. Rai +1
Via nonlocality distillation, a number of copies of a given nonlocal correlation can be turned into a new correlation displaying a higher degree of nonlocality. Apart from its clea…
Geometry of the quantum set on no-signaling faces
Ashutosh Rai, Cristhiano Duarte, Samurai Brito +1
Since Bell's theorem we know that quantum mechanics is incompatible with local hidden-variable models, the phenomenon known as quantum nonlocality. However, despite steady progress…
Greenberger-Horne-Zeilinger state generation with linear optical elements
Bertúlio de Lima Bernardo, M. Lencśes, S. Brito +1
We propose a scheme to probabilistically generate Greenberger-Horne-Zeilinger (GHZ) states encoded on the path degree of freedom of three photons. These photons are totally indepen…
Concentration phenomena in the geometry of Bell correlations
Cristhiano Duarte, Samuraí Brito, Barbara Amaral +1
Bell's theorem shows that local measurements on entangled states give rise to correlations incompatible with local hidden variable models. The degree of quantum nonlocality is not…
Scaling properties of d-dimensional complex networks
Samuraí Brito, Thiago C. Nunes, Luciano R. da Silva +1
The area of networks is very interdisciplinary and exhibits many applications in several fields of science. Nevertheless, there are few studies focusing on geographically located $…
Machine learning non-local correlations
Askery Canabarro, Samuraí Brito, Rafael Chaves
The ability to witness non-local correlations lies at the core of foundational aspects of quantum mechanics and its application in the processing of information. Commonly, this is…
Quantifying Bell non-locality with the trace distance
S. G. A. Brito, B. Amaral, R. Chaves
Measurements performed on distant parts of an entangled quantum state can generate correlations incompatible with classical theories respecting the assumption of local causality. T…
Role of dimensionality in preferential attachment growth in the Bianconi-Barabási model
Thiago C. Nunes, Samurai Brito, Luciano R. da Silva +1
Scale-free networks are quite popular nowadays since many systems are well represented by such structures. In order to study these systems, several models were proposed. However, m…
Role of dimensionality in complex networks: Connection with nonextensive statistics
S. G. A. Brito, L. R. da Silva, Constantino Tsallis
Deep connections are known to exist between scale-free networks and non-Gibbsian statistics. For example, typical degree distributions at the thermodynamical limit are of the form…
