Tailoring discrete quantum walk dynamics via extended initial conditions: Towards homogeneous probability distributions
Germán J. de Valcárcel, Eugenio Roldán, Alejandro Romanelli
We study the evolution of initially extended distributions in the coined quantum walk on the line by analyzing the dispersion relation of the process and its associated wave equati…
Spontaneous symmetry breaking as a resource for noncritically squeezed light
G. J. de Valcárcel, F. V. Garcia-Ferrer, R. M. Höppner +3
In the last years we have proposed the use of the mechanism of spontaneous symmetry breaking with the purpose of generating perfect quadrature squeezing. Here we review previous wo…
Noncritical quadrature squeezing through spontaneous polarization symmetry breaking
Ferran V. Garcia-Ferrer, Carlos Navarrete-Benlloch, Germán J. de Valcárcel +1
We discuss the possibility of generating noncritical quadrature squeezing by spontaneous polarization symmetry breaking. We consider first type-II frequency-degenerate optical para…
