Topological quantum computing: The quest for a quality qubit
: Information is stored non-locally, meaning local disturbances—like environmental noise or heat—cannot easily flip a qubit's state. This hardware-level protection could theoretically eliminate the massive overhead required for active error correction in other quantum systems. Topological Quantum Computation and Quantum Com...
As of , the field is transitioning from theoretical milestones to engineering prototype validation: Topological quantum computing: The quest for a quality
: Operations are discrete—you either completed a braid or you didn't. This reduces "over-rotation" or "under-rotation" errors common in analog-controlled quantum systems. Status and Outlook (2026) Topological Quantum Computation and Quantum Com...
