  We report superconductivity in quasi-1D nanostructures created at the
LaAlO3/SrTiO3 interface. Nanostructures having line widths w~10 nm are formed
from the parent two-dimensional electron liquid using conductive atomic force
microscope lithography. Nanowire cross-sections are small compared to the
superconducting coherence length in LaAlO3/SrTiO3 (w<<xi~100 nm), placing them
in the quasi-1D regime. Broad superconducting transitions with temperature and
finite resistances in the superconducting state well below Tc~200 mK are
observed. V-I curves show switching between the superconducting and normal
states that are characteristic of superconducting nanowires. The four-terminal
resistance in the superconducting state shows an unusual dependence on the
current path, varying by as much as an order of magnitude.
