  The cosmological constant $\Lambda$ can be achieved as the result of
entangled and statistically correlated minisuperspace cosmological states,
built up by using a minimal choice of observable quantities, i.e. $\Omega_{m}$
and $\Omega_{k}$, which assign the cosmic dynamics. In particular, we consider
a cosmological model where two regions, corresponding to two correlated eras,
are involved; the present universe description would be, in this way, given by
a density matrix $\hat \rho$, corresponding to an entangled final state.
Starting from this assumption, it is possible to infer some considerations on
the cosmic thermodynamics by evaluating the Von Neumann entropy. The
correlation between different regions by the entanglement phenomenon results in
the existence of $\Lambda$ (in particular $\Omega_{\Lambda}$) which could be
interpreted in the framework of the recent astrophysical observations. As a
byproduct, this approach could provide a natural way to solve the so called
coincidence problem.
