  In this erratum, we revisit the issue of bulk-disorder on proposals to
realize an effective p+ip superconductor from spin-orbit coupled materials.
Contrary to the claim in [Phys. Rev. B 83, 184520 (2011)], we show that the
pair breaking effects of bulk-disorder are negligible, and that bulk disorder
does not suppress the induced superconductivity. This argument does not apply
to our conclusions regarding impurities residing in the spin-orbit coupled
material or disorder at the interface to the bulk superconductor, both of which
tend to suppress superconductivity unless spin-orbit coupling is large.
