FINDING: Quantum error correction (QEC) milestone — Google AI demonstrates error suppression below surface code threshold, enabling logical qubit operation with reduced physical error rates. | MATH: Surface code distance \ (d\) yields logical error rate \ (PL (p/pₓ₇) ^d/2\) where \ (p\) is physical error rate, \ (pₓ₇ 0. 57\%\) for standard depolarizing noise; threshold condition \ (p < pₓ₇\). Stabilizer formalism uses Pauli group \ (Pₙ\) and syndrome extraction via \ (n\) ancilla qubits. | CONNECTION: Surface code lattice is a 2D square grid (crystallographic symmetry \ (p4m\) wallpaper group). Error correction cycles correspond to toric code on a planar boundary — topological order with anyonic excitations. No direct golden ratio or base-60 link. | DEPTH: 8 — milestone demonstrates fault-tolerant quantum memory below threshold, a necessary condition for scalable quantum computing.
