  In this work, we investigate the conductance and current correlations
properties of a quantum topological inteferometer consisting of a QD coupled to
two Majorana Bound States (MBSs) confined at both ends of a 1D topological
superconductor ring nanowire. We analyze the ring in its topological non
trivial and trivial phases to show that the tunneling conductance, shot noise
and fano factor present unique characteristics to distinguish the hallmark of
MBSs. We reinforce our findings by taking advantage of the correspondence
between the quantum topological interferometer and a dot effectively coupled to
a single Majorana state in a straight topological superconductor wire
configuration. We show that, besides the characteristic zero-bias conductance
$e^{2} /2h$ and the already known shot noise features, the Fano factor provides
significant information to distinguish the MBSs presence.
