Spin quantum correlations of relativistic particles

Pablo L. Saldanha, Vlatko Vedral

We show that a pair of massive relativistic spin-1/2 particles prepared in a maximally entangled spin state in general is not capable of maximally violating the Clauser-Horne-Shimo…

Physical interpretation of the Wigner rotations and its implications for relativistic quantum information

Pablo L. Saldanha, Vlatko Vedral

We present a new treatment for the spin of a massive relativistic particle in the context of quantum information based on a physical interpretation of the Wigner rotations, obtaini…

Energy and momentum entanglement in parametric downconversion

Pablo L. Saldanha, C. H. Monken

We present a simple treatment for the phenomenon of parametric downconversion considering the coherent scattering of one pump photon into a photon pair by a nonlinear crystal. The…

Estimating the reduction time of quantum states

Fernando Parisio

An effective description of microscopic measurements is given, in which the precise moment of probing is not determined. Within this scenario we propose a scheme that relies on an…

Enhanced four-wave mixing via crossover resonance in cesium vapor

T. Passerat de Silans, C. S. L. Goncalves, D. Felinto +1

We report on the observation of enhanced four-wave mixing via crossover resonance in a Doppler broadened cesium vapor. Using a single laser frequency, a resonant parametric process…

Electromagnetically induced transparency in inhomogeneously broadened Lambda-transition with multiple excited levels

O. S. Mishina, M. Scherman, P. Lombardi +7

Electromagnetically induced transparency (EIT) has mainly been modelled for three-level systems. In particular, a considerable interest has been dedicated to the Lambda-configurati…
