  We consider a quantum impurity immersed in a dipolar Bose Einstein condensate
and study the properties of the emerging polaron. We calculate the energy,
effective mass and quasi-particle residue of the dipolar polaron and
investigate their behaviour with respect to the strength of zero-range contact
and a long-range dipolar interactions among the condensate atoms and with the
impurity. While quantum fluctuations in the case of pure contact interactions
typically lead to an increase of the polaron energy, dipole-dipole interactions
are shown to cause a sign reversal. The described signatures of dipolar
interactions are shown to be observable with current experimental capabilities
based on quantum gases of atoms with large magnetic dipole moments such as
Erbium or Dysprosium condensates.
