Generic Entanglement and Standard Form for N-mode Pure Gaussian States
Gerardo Adesso
abstract: We investigate the correlation structure of pure N-mode Gaussian resources
which can be experimentally generated by means of squeezers and beam splitters,
whose entanglement properties are generic. We show that those states are
specified (up to local unitaries) by N(N-1)/2 parameters, corresponding to the
two-point correlations between any pair of modes. Our construction yields a
practical scheme to engineer such generic-entangled N-mode pure Gaussian states
by linear optics. We discuss our findings in the framework of Gaussian matrix
product states of harmonic lattices, raising connections with entanglement
frustration and the entropic area law.
