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 ...

Characterization of source rocks and groundwater radioactivity at the Chihuahua valley
(Sociedad Mexicana de Física, 2007)
As part of a scientific research project about alpha radioactivity in groundwater for human consumption at the Chihuahua City, the charac-terization of rock sources of radioactivity around de Chihuahua valley was developed. ...

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 ...

A three-dimensional model for the dispersion of radioactive substances in marine ecosystems: application to the Baltic Sea after the Chernobyl disaster
(Elsevier, 2004)
A 3-D dispersion model has been developed to simulate the dispersion of nuclear contaminants in marine ecosystems. This model is characterized by presenting high spatial resolution, by taking into account the possible ...

Introducción a la lógica cuántica
(Consejo Superior de Investigaciones Científicas, CSIC, 2000)
En este trabajo trataremos de responder las siguientes preguntas: 1. ¿Qué entendemos por «lógica» de una teoría física? 2. ¿Cuál es la lógica de la física clásica? 3. ¿Cómo se puede construir una lógica basada en la mecánica ...

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 ...
