  We consider a quantum dot coupled to a topological superconductor and two
normal leads and study transport properties of the system. Using Keldysh
path-integral approach, we study current fluctuations (shot noise) within the
low-energy effective theory. We argue that the combination of the tunneling
conductance and the shot noise through a quantum dot allows one to distinguish
between the topological (Majorana) and non-topological (e.g., Kondo) origin of
the zero-bias conduction peak. Specifically, we show that, while the tunneling
conductance might exhibit zero-bias anomaly due to Majorana or Kondo physics,
the shot noise is qualitatively different in the presence of Majorana zero
modes.
