Query: Optical Manipulation of Single Flux Quanta   Magnetic field can penetrate into type-II superconductors in the form of
Abrikosov vortices, which are magnetic flux tubes surrounded by circulating
supercurrents often trapped at defects referred to as pinning sites. Although
the average properties of the vortex matter can be tuned with magnetic fields,
temperature or electric currents, handling of individual vortices remains
challenging and has been demonstrated only with sophisticated magnetic force,
superconducting quantum interference device or strain-induced scanning local
probe microscopies. Here, we introduce a far-field optical method based on
local heating of the superconductor with a focused laser beam to realize a
fast, precise and non-invasive manipulation of individual Abrikosov vortices,
in the same way as with optical tweezers. This simple approach provides the
perfect basis for sculpting the magnetic flux profile in superconducting
devices like a vortex lens or a vortex cleaner, without resorting to static
pinning or ratchet effects. Since a single vortex can induce a Josephson phase
shift, our method also paves the way to fast optical drive of Josephson
junctions, with potential massive parallelization of operations.
