Violating bell's inequality beyond Cirel'son's bound
(American Physical Society, 2002-02-11)
Cirel’son inequality states that the absolute value of the combination of quantum correlations appearing in the Clauser-Horne-Shimony-Holt (CHSH) inequality is bound by 2 √ 2. It is shown that the correlations of two qubits ...

Quantum social networks
(IOP Science, 2012)
We introduce a physical approach to social networks (SNs) in which each actor is characterized by a yes–no test on a physical system. This allows us to consider SNs beyond those originated by interactions based on ...

Physico-chemical modeling of positive corona discharge in carbon dioxide
(Institute of Electrical and Electronics Engineers (IEEE), 2010)
Positive wire-to-cylinder corona discharge in pure CO2 has been simulated using a model that includes elementary plasma processes (ionization, electron attachment and detachment, ion recombination, etc.) and chemical ...

Proposed experiment for the quantum "Guess My Number" protocol
(American Physical Society, 2005)
An experimental realization of the entanglement-assisted “Guess My Number” protocol for the reduction of communication complexity, introduced by Steane and van Dam, would require producing and detecting three-qubit GHZ ...

Research facilities and highlights at the Centro Nacional de Aceleradores (CNA)
(Springer, 2021)
The Centro Nacional de Aceleradores is a user-oriented accelerator facility in Seville, Spain. Its main facilities are a 3 MV tandem accelerator, an 18 MeV proton Cyclotron, a tandetron used for AMS, a compact accelerator ...

The use of changes in small coastal Atlantic brooks in southwestern Europe as indicators of anthropogenic and climatic impacts over the last 400 years
(Springer Nature, 2015)
Unlike other aquatic continental ecosystems such as lakes, small coastal brooks have not been used as indicators of anthropogenic or climatic impacts. Our study addresses reconstructing the evolution of coastal brooks in ...

Effects of particle size and field orientation on the yield stress of magnetostabilized fluidized beds
(American Chemical Society, 2012-05-23)
In this work, we present experimental measurements of the yield stress of gas-fluidized beds of magnetizable particles stabilized by an externally imposed magnetic field. Powder samples consist of spherical magnetite ...

Quantum key distribution in the Holevo limit
(American Physical Society, 2000-12-25)
A theorem by Shannon and the Holevo theorem impose that the efficiency of any protocol for quantum key distribution, E , defined as the number of secret (i.e., allowing eavesdropping detection) bits per transmitted bit ...

Two qubits of a W state violate Bell's inequality beyond Cirel'son's bound
(American Physical Society, 2002-10)
It is shown that the correlations between two qubits selected from a trio prepared in a W state violate the Clauser-Horne-Shimony-Holt inequality more than the correlations between two qubits in any quantum state. Such a ...

Characterisation of the intra-annual rainfall and its evolution (1837-2010) in the southwest of the Iberian Peninsula
(Springer Nature, 2013)
Variability in precipitation affects annual total records and causes instability in rainfall distribution throughout the year. Our aim in this study was to develop a procedure, based on pluviometric centralisation and ...
