- Abstract: Gradual loss of the entanglement of a twin beam containing around 25 photon
pairs with the increasing external noise is experimentally investigated. The
entanglement is quantified by the non-classicality depths and the
non-classicality counting parameters related to several non-classicality
criteria. The reduction of intensity moments of the analyzed multi-mode twin
beams to single-mode ones allows to determine the negativity as another
quantifier of the entanglement. Both the raw photocount histograms and the
reconstructed photon-number distributions are analyzed in parallel.

We study a system of two interacting, non-indentical quantum emitters driven by a coherent field.

Numerous non-classicality criteria based on the probabilities of experimental photocount or theoretical photon-number distributions are derived.
They are grouped into parametric systems that allow the analysis of the non-classicality from different points of view.
For comparison, the derived criteria are applied both to an experimental photocount histogram of a twin beam and the reconstructed photon-number distributions with different levels of the noise.

In spite of particle losses the quantum entanglement propagation exhibits a ballistic character with propagation speeds related to the differerent quasiparticles that are involved in the dynamics.
Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.
