⚛️ Tetron-Based Fault-Tolerant Quantum Computation Roadmap

Microsoft Quantum outlines a roadmap toward fault-tolerant quantum computing using topological qubits called tetrons, focusing on Majorana zero modes. The roadmap details four generations of devices, from single-qubit benchmarking to a topological qubit array that can perform quantum error correction demonstrations. The devices rely on a superconductor-semiconductor heterostructure, quantum dots, and a microwave readout system. The document describes the design and protocols needed for demonstrating single-qubit benchmarking, Clifford gate execution, and quantum error detection and correction, all tailored to the unique properties of topological qubits. The strategy prioritizes measurement-based braiding transformations and lattice surgery, showcasing the non-Abelian nature of MZMs. The outlined approach aims for utility-scale quantum computation by leveraging topological protection to reduce errors and simplify control.
