N2 - We suggest flux quantum-based force realization in the sub-pico-Newton range. By controlling the number of flux quantum in a superconducting ring, a force can be created as an integer multiple of a constant force step. For a 70 nmthick Nb ring with the inner and outer radii of 5 μm and 10 μm, respectively, the force step is estimated to be 186 fN, assuming the magnetic field gradient of 10 T/m. We also estimated a maximum force limit and addressed the stability of force realization against thermal fluctuation.
