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...
: 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. Topological quantum computing: The quest for a quality
: 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. not the precise path taken.
