  Semiconducting nanowire Josephson junctions represent an attractive platform
to investigate the anomalous Josephson effect and detect topological
superconductivity by studying Josephson supercurrent. However, an external
magnetic field generally suppresses the supercurrent through hybrid nanowire
junctions and significantly limits the field range in which the supercurrent
phenomena can be studied. In this work, we investigate the impact of the length
of InSb-Al nanowire Josephson junctions on the supercurrent resilience against
magnetic fields. We find that the critical parallel field of the supercurrent
can be considerably enhanced by reducing the junction length. Particularly, in
30 nm-long junctions supercurrent can persist up to 1.3 T parallel field -
approaching the critical field of the superconducting film. Furthermore, we
embed such short junctions into a superconducting loop and obtain the
supercurrent interference at a parallel field of 1 T. Our findings are highly
relevant for multiple experiments on hybrid nanowires requiring a magnetic
field-resilient supercurrent.
