Hierarchical quantum code
Hierarchical quantum code is represented at T1 by concatenation of the seven-qubit HGP member with the L=2 surface code. The deterministic constructor validates the binary symplectic quotient and derives the displayed operator-incidence view from those same checks. Decoder, operation, relation, and realization facets remain unsurveyed.
