Topological Quantum Computing (TQC) is a specialized approach to quantum computation that uses "braiding" patterns of exotic quasiparticles called to store and process information . Unlike standard quantum systems that are highly sensitive to noise, TQC is inherently fault-tolerant because its information is protected by the global "shape" (topology) of the system rather than individual particle states. Core Features of Topological Quantum Computation

: 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. Status and Outlook (2026)
: 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...
