Controlling both the amplitude and phase of the quantum order parameter({\psi}) in nanostructures is important for next-generation information andcommunication technologies. The long-range coherence of attractive electrons insuperconductors render these materials as a nearly ideal platform for suchapplications. To-date, control over {\psi} has remained limited to themacroscopic scale, either by adjusting untunable materials properties, such asfilm thickness, stoichiometry and homogeneity or by tuning external magneticfields. Yet, although local tuning of {\psi} is desired, the lack of electricresistance in superconductors, which may be advantageous for some technologieshinders convenient voltage-bias tuning. Likewise, challenges related tonanoscale fabrication of superconductors encumber local tunability of {\psi}.Here, we demonstrate local tunability of {\psi}, obtained by patterning with asingle lithography step a Nb nano superconducting quantum interference device(nano-SQUID) that is biased at its nano bridges. Our design helped us revealalso unusual electric characteristics-effective zero inductance, which ispromising for quantum technologies and nanoscale magnetic sensing. Finally, weaccompanied our experimental results by a semi-classical model, which not onlyis extending the applicability of our devices, but is also useful fordescribing planar nano-SQUIDs in general.
