Abstract
We propose and analyze a nanoengineered vortex array in a thin-film type-II superconductor as a magnetic lattice for ultracold atoms. This proposal addresses several of the key questions in the development of atomic quantum simulators. By trapping atoms close to the surface, tools of nanofabrication and structuring of lattices on the scale of few tens of nanometers become available with a corresponding benefit in energy scales and temperature requirements. This can be combined with the possibility of magnetic single site addressing and manipulation together with a favorable scaling of superconducting surface-induced decoherence.

Superconductor as Nanolattice of Atom Traps
Published 4 October 2013
A proposed experiment would trap atoms in a nanoscale magnetic field pattern produced by a superconductor—an arrangement that could perform some kinds of quantum computing.
