Superconductor/Semiconductor Devices for Majorana Zero Modes

There is growing interest in material systems that both support Majorana zero modes (MZMs), relevant for quantum computing, and can be fabricated into complex and scalable geometries. So far, MZMs have been tentatively identified in individual InSb or InAs nanowires with induced superconductivity. Future tests of non-Abelian statistics will likely involve braiding or interferometric measurement, requiring branched or looped geometries, challenging to realize using individual nanowires.
