Non-gaussian Entanglement Swapping between Three-Mode Spontaneous Parametric Down Conversion and Three Qubits
A. Agustí Casado, C. Sabín
In this work we study the production and swapping of non-gaussian multipartite entanglement in a setup containing a parametric amplifier which generates three photons in different…
Wigner representation for polarization-momentum hyperentanglement generated in parametric down conversion, and its application to complete Bell-state measurement
A. Casado, S. Guerra, J. Plácido
We apply the Wigner function formalism to the study of two-photon polarization-momentum hyperentanglement generated in parametric down conversion. It is shown that the consideratio…
A Local Hidden Variables Model for Experiments involving Photon Pairs Produced in Parametric Down Conversion
Alberto Casado, Trevor Marshall, Ramon Risco-Delgado +1
In previous articles we have developed a theory of down conversion in nonlinear crystals, based on the Wigner representation of the radiation field. Taking advantage of the fact th…
Local Realistic Theory for PDC Experiments Based on the Wigner Formalism
Alberto Casado, Ramon Risco-Delgado, Emilio Santos
In this article we present a local hidden variables model for all experiments involving photon pairs produced in parametric down conversion, based on the Wigner representation of t…
Type-II parametric down conversion in the Wigner-function formalism. Entanglement and Bell's inequalities
Alberto Casado, Trevor W. Marshall, Emilio Santos
We continue the analysis of our previous articles which were devoted to type-I parametric down conversion, the extension to type-II being straightforward. We show that entanglement…
