Quantum-Transport Exploration of Design Space for Majorana Zero Modes in Finite Kitaev Chains

Quantum transport simulations are employed to investigate the properties of short finite Kitaev chains, with a focus on exploring the possible design space. We numerically investigate how the Kitaev chain behaves when system parameters are varied and study the transport characteristics, including direct tunneling and Andreev processes. We examine how the chain length provides topological protection of Majorana zero modes (MZMs) and demonstrate how increasing the length alleviates Majorana oscillations that could be detrimental for topological quantum computing with MZMs.
