  By calculating the differential tunneling conductance spectra from the two
ends of a Majorana nanowire with a quantum dot embedded at one end, we
establish that a careful examination of the nonlocal correlations of the zero
bias conductance peaks, as measured separately from the two ends of the wire,
can distinguish between topological Majorana bound states and trivial Andreev
bound states. In particular, there will be identical correlated zero bias peaks
from both ends for Majorana bound states, and thus the presence of correlated
zero bias conductance from the two wire ends could imply the presence of
topological Majorana zero modes in the system. On the contrary, there will not
be identical correlated zero bias peaks from both ends for Andreev bound
states, so the absence of correlated zero bias conductance from the two wire
ends implies the absence of topological Majorana zero modes in the system. We
present detailed results for the calculated conductance, energy spectra, and
wavefunctions for different chemical potentials at the same magnetic field
values to motivate end-to-end conductance correlation measurements in Majorana
nanowires.
