| contents | We develop the quantum component of Algebraic Phase Theory by showing that quantum phase, Weyl noncommutativity, and stabiliser codes arise as unavoidable algebraic consequences of Frobenius duality. Working over finite commutative Frobenius rings, we extract nondegenerate phase pairings, Weyl operator algebras, and quantum stabiliser codes directly from admissible phase data, without assuming Hilbert spaces, analytic inner products, or an externally imposed symplectic structure.
Within this framework, quantum state spaces appear as minimal carriers of faithful phase action, and stabiliser codes are identified canonically with self-orthogonal submodules under the Frobenius phase pairing. CSS-type constructions arise only as a special splitting case, while general Frobenius rings admit intrinsically non-CSS stabilisers. Nilpotent and torsion structure in the base ring give rise to algebraically protected quantum layers that are invisible to admissible Weyl-type errors.
These results place quantum stabiliser theory within Algebraic Phase Theory: quantisation emerges as algebraic phase induction rather than analytic completion, and quantum structure is information-complete at the level of algebraic phase relations alone. Throughout, we work over finite Frobenius rings, which are precisely the base rings for which admissible phase data become strongly admissible, and in this regime the full quantum formalism is forced by Frobenius duality. |
