Axioms originally formulated within: A New Axiomatization of Unified Quantum Logic by M. Pavicic.
i.
Logical Connectives: ¬, →, ∨, ∧
ii.
Propositions: p, q, r, ...
i.
If p is a Proposition in ZQL, p is a WFF.
ii.
If p is a WFF, so is ¬p.
iii.
If p, q are WFF, so is p → q.
iv.
If p, q are WFF, so is p v q.
v.
If p, q are WFF, so is p ∧ q.
vi.
There are no other WFF of ZQL.
[A1]
A → A
[A2]
A → ¬¬A ∧ ¬¬A → A
[A3]
A → A ∨ B
[A4]
B → A ∨ B
[A5]
B → A ∨ ¬A
[R1]
(A → B), (B → C) | A → C
[R2]
(A → B) | (¬B → ¬A)
[R3]
(A → C), (B → C) | (A v B → C)
[R4a]
(B v ¬B) → A | A
[R4b]
A | (B v ¬B) → A
