Scalable quantum computing with Majorana-based topological qubits

We present progress in implementing a scalable quantum computing architecture based on tetron qubits. This approach leverages gate-defined hybrid superconductor-semiconductor nanowires hosting Majorana zero modes and employs interferometric parity readout loops to realize orthogonal projective measurements—a critical capability for measurement-based topological quantum computing. Our single-shot parity readout results demonstrate the feasibility of this approach and highlight contrasting stability mechanisms for different measurement axes. In this talk, we will discuss design concepts, tuning strategies, and emerging performance trends, as well as outline pathways to extend coherence and improve fidelity in future implementations.
