  We consider a p-wave superconductor wire coupled to two metallic rings.
confined to a one-dimensional wire. At the two interface between the the wire
and the metallic rings the pairing order parameter vanishes, as result two zero
modes Majorana fermion appear. The two metallic rings are pierced by external
magnetic fluxes. The special features of the Majorana Fermions can be deduced
from the correlation between the currents in the two rings.
