Such a relation is necessary to actually measure the entanglement entropy. We show that in general, the Shannon entropy of the probability distribution of certain symmetry observables gives a lower bound to the entropy. In some cases this bound is

We find that when the QD-QPC interaction is weak, the width of the resonance at the Fermi level is hardly affected by it, suggesting the absence of dephasing. However, the spectral weight of such resonance is reduced leading to an observable suppression of the conductance and the elastic transmission probability through the QD.
