The positions of Abrikosov vortices have long been considered
as
means to encode classical information. Although it is possible to
move individual vortices using local probes, the challenge of scalable
on-chip vortex-control remains outstanding, especially when considering
the demands of controlling multiple vortices. Realization of vortex
logic requires means to shuttle vortices reliably between engineered
pinning potentials, while concomitantly keeping all other vortices
fixed. We demonstrate such capabilities using Nb loops patterned below
a NbSe2layer. SQUID-on-Tip (SOT) microscopy
reveals that the loops localize vortices in designated sites to a
precision better than 100 nm; they realize “push” and
“pull” operations of vortices as far as 3 μm.
Successive application of such operations shuttles a vortex between
adjacent loops. Our results may be used as means to integrate vortices
in future quantum circuitry. Strikingly, we demonstrate a winding
operation, paving the way for future topological quantum computing
and simulations.
