Abstract

We present a new concept of force realization, flux quantum-based mechanism in the sub-pico-Newton range. By controlling the number of flux quantum in a superconducting ring, a force can be generated as an integer multiple of a constant force step. For a 50 nm-thick Nb annulus with the inner and outer radii of 5 μm and 10 μm, respectively, and the field gradient of 10 T/m the force step is estimated to be 184 fN. Realization procedure, feasibility, and the stability against thermal fluctuations are also addressed. Copyright
