Abstract :
Summary form only given. Drawing on recent advances in the treatment of continuous variable systems, we propose two systems that can be used to observe Bell-type correlations between the continuous variables of their sub-systems. A set of polarisation dependent measurements of the quadrature amplitude and phase of a system can be used to construct a correlation parameter that we shall denote B. We take B > 2 to indicate Bell-type (or strong, nonclassical) correlations, which may be used as a resource in quantum information experiments.
