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.

: Because the quantum state is protected by an energy gap and topological rules, these qubits are predicted to have exceptionally long coherence times compared to superconducting circuits. As of , the field is transitioning from

: Computations are performed by moving anyons around each other. These paths form "braids" in spacetime; the outcome of the calculation depends only on the sequence of these crossings, not the precise path taken.
