  A versatile control of magnetic systems, widely used to store information,
can also enable manipulating Majorana bounds states (MBS) and implementing
fault-tolerant quantum information processing. The proposed platform relies on
the proximity-induced superconductivity in a two-dimensional electron gas
placed next to an array of magnetic tunnel junctions (MTJs). A change in the
magnetization configuration in the MTJ array creates tunable magnetic textures
thereby removing several typical requirements for MBS: strong spin-orbit
coupling, applied magnetic field, and confinement by one-dimensional structures
which complicates demonstrating non-Abelian statistics through braiding. Recent
advances in fabricating two-dimensional epitaxial superconductor/semiconductor
heterostructures and designing tunable magnetic textures support the
feasibility of this novel platform for MBS.
