Andreev spin qubits bound to Josephson vortices in spin-orbit coupled planar Josephson junctions

Katharina Laubscher, Valla Fatemi, Jay D. Sau

We propose a variant of Andreev spin qubits (ASQs) defined in planar Josephson junctions based on spin-orbit coupled two-dimensional electron gases (2DEGs) in a weak out-of-plane m…
