Experimental investigation of initial system-environment correlations via trace-distance evolution / A. Smirne, D. Brivio, S. Cialdi, B. Vacchini, M. Paris. - In: PHYSICAL REVIEW A. - ISSN 1050-2947. - 84:3(2011), pp. 032112.032112-1-032112.032112-5. [10.1103/PhysRevA.84.032112]
Abstract:
The trace distance between two states of an open quantum system quantifies their distinguishability and, for a fixed environmental state, can increase above its initial value only in the presence of initial system-environment correlations. We provide experimental evidence of such a behavior. In our all-optical apparatus, we exploit spontaneous parametric down conversion as a source of polarization entangled states and a spatial light modulator to introduce in a general fashion correlations between the polarization and the momentum degrees of freedom, which act as environment.
