Fault Tolerance with the ZX-Calculus and Fusion Complexes: Tools for QEC Development

Explore fault tolerance frameworks for quantum error correction in this 32-minute talk by Naomi Nickerson from PsiQuantum. Delve into two unifying approaches that bridge hardware-specific models with underlying code structures: a ZX calculus-based framework and fusion complexes. Discover how these tools connect circuit-based, measurement-based, fusion-based quantum computation, and Floquet codes to a common stabilizer fault-tolerance structure. Learn about the topological interpretation of fault tolerance under circuit-level error models and see practical applications in designing photonic architectures. Gain insights into developing quantum error correction methods for various qubit technologies, including ions, photons, and superconducting qubits.
