Non-Gaussianity and purity in finite dimension / M. G. Genoni, M. Paris. - In: INTERNATIONAL JOURNAL OF QUANTUM INFORMATION. - ISSN 0219-7499. - 7:suppl.(2009), pp. 97-103.
Abstract:
We address truncated states of continuous variable systems and analyze their statistical
properties numerically by generating random states in finite-dimensional Hilbert spaces.
In particular, we focus to the distribution of purity and non-Gaussianity for dimension
up to d = 21. We found that both quantities are distributed around typical values
with variances that decrease for increasing dimension. Approximate formulas for typical
purity and non-Gaussianity as a function of the dimension are derived.
