Quantum devices built on hybrid superconductor-semiconductor material platforms are a predicted host for a variety of exotic quantum states. The experimental realization of these states, however, has proven to be a formidable challenge. Here, I present two novel device architectures which seek to address this challenge. To begin, I demonstrate the first successful realization of 1D ballistic transport in a non-van der Waals (vdW) material, here an InSb nanoribbon, controlled with an all-vdW gate stack. I show that the reduced disorder of this gating approach results in improved transport quality, and offers a promising route forward for disorder-sensitive nanowire-based Majorana zero mode devices. Additionally, I show that the use of a nanoribbon, itself a novel nanowire alternative, introduces magnetic field angle-tunability to the effective g-factor. Finally, I will discuss my ongoing work to realize a multiterminal Josephson quantum dot (MTJQD), consisting of a quantum dot coupled to multiple superconducting terminals. Like more traditional multiterminal Josephson junctions (MTJJs), such MTJQDs are predicted to host a rich spectrum of subgap states, which may be topologically non-trivial. However, the inherent tunability of couplings in the quantum dot architecture provides an elegant solution to the lack of control of the scattering region which currently limits conventional MTJJ experiments.
