We study two-terminal configurations in junctions between a topologicalsuperconducting wire with spin-orbit coupling and magnetic field, and anordinary conductor with an embedded quantum dot. One of the signatures of theMajorana zero modes in the topological phase is a quantization of the zero-biasconductance at $G(V=0)=2e^2/h$. However, the finite size of the wires and thepresence of the quantum dot in the junction generate more complicated featureswhich lead to deviations from this simple picture. Here, we analyze thebehavior of the conductance at zero and finite bias, $G(V)$, as a function of agate voltage applied at the quantum dot in the case of a finite-length wire. Weanalyze the effect of the angle between the magnetic field and the orientationassociated to the spin-orbit coupling. We provide a detailed description of thespectral features of the quantum wire weakly and also strongly coupled to thequantum dot and describe the conditions to have zero-energy states in these tworegimes for both the topological and non-topological phases. We also analyzethe concomitant behavior of the noise. We identify qualitative features thatare useful to distinguish between the topological and non-topological phases.We show that in a strongly coupled quantum dot the simultaneous hybridizationwith the topological modes and the supragap states of the wire mask thesignatures of the Majorana bound states in both the conductance and the Fanofactor.
