Twist-defect surface code
Twist-defect surface code is represented at T1 by seven-qubit surface-code twist representative with mixed Pauli check at the dislocation. The deterministic constructor validates the binary symplectic quotient and derives the displayed operator-incidence view from those same checks. Decoder, operation, and realization facets remain unsurveyed.
