  Recently a new formulation of quantum mechanics has been introduced, based on
signed classical field-less particles interacting with an external field by
means of only creation and annihilation events. In this paper, we extend this
novel theory to the case of many-body problems. We show that, when restricted
to spatial finite domains and discrete momentum space, the proposed extended
theory is equivalent to the time-dependent many-body Wigner Monte Carlo method.
In this new picture, the treatment of entangled systems comes naturally and,
therefore, we apply it to the study of quantum entangled systems. The latter is
represented in terms of two Gaussian wave packets moving in opposite
directions. We introduce the presence of a dissipative background and show how
the entanglement is affected by different (controlled) configurations.
