We propose and analyze neutral atom traps generated by vortices imprinted bymagnetic field pulse sequences in type-II superconducting disks and rings. Wecompute the supercurrent distribution and magnetic field resulting from thevortices in the superconductor. Different patterns of vortices can be writtenby versatile loading field sequences. We discuss in detail procedures togenerate quadrupole traps, self-sufficient traps and ring traps based onsuperconducting disks and rings. The ease of creating these traps and the lowcurrent noise in supercurrent carrying structures makes our approach attractivefor designing atom chip interferometers and probes.
