Claim 0:
1. A method of fabricating a device, the method comprising:
obtaining a substrate;
forming a superconducting quantum interference device (SQUID) on an upper surface of the substrate, wherein the SQUID comprises a superconductor trace and at least one Josephson junction interrupting a path of the superconductor trace;
forming a dielectric capping layer on an upper surface of the SQUID; and
patterning the dielectric capping layer to create an opening through which a first region of the SQUID is exposed, the first region of the SQUID comprising a first Josephson junction, wherein the dielectric capping layer covers a majority of the superconductor trace of the SQUID.
