We propose a tomographic approach to the study of quantum nonlocality in continuously variable quantum systems. On one hand we derive a Bell-like inequality for measured tomograms, and on the other we introduce pseudospin operators whose statistics can be inferred from the data characterizing the reconstructed state, thus giving the possibility of using standard Bell inequalities. Illuminating examples are also discussed.

Abstract
We propose a tomographic approach to the study of quantum nonlocality in continuously variable quantum systems. On one hand we derive a Bell-like inequality for measured tomograms, and on the other we introduce pseudospin operators whose statistics can be inferred from the data characterizing the reconstructed state, thus giving the possibility of using standard Bell inequalities. Illuminating examples are also discussed.File in questo prodotto:
