6.25. QuantumBlockEncoding/ReversibleClassical.lean🔗

7 explicit public declarations, in source order.

Definition6.25.1

uses 0used by 0✓L∃∀N

Plain-English reading. This type lists the allowed alternatives for “reversible gate”; its constructors are the cases that downstream code must handle.

Formal status. Compiled declaration in the default ASPBE import surface; its kind and displayed Lean type determine how it may be used.

Why it is in this chapter. Circuit and register semantics, reusable tensor-train and matrix constructions, and explicit exact-real storage-cost refinements. Each declaration's hypotheses and conclusion fix its certified scope.

Technical source note. The source declaration has no docstring. The reader cue above is generated from its kind and name and does not replace the Lean signature.

Declaration kind. inductive.

Source: QuantumBlockEncoding/ReversibleClassical.lean:14. A commit-pinned external link is added by the publication build when the source exists at the published ref.

Definition6.25.2

uses 0used by 0✓L∃∀N

Plain-English reading. This abbreviation gives a shorter name to the type or expression used for “reversible program”.

Formal status. Compiled declaration in the default ASPBE import surface; its kind and displayed Lean type determine how it may be used.

Technical source note. The source declaration has no docstring. The reader cue above is generated from its kind and name and does not replace the Lean signature.

Definition6.25.3

uses 0used by 0✓L∃∀N

Plain-English reading. This definition gives the library's named construction or computation for “ccx basis action”.

Formal status. Compiled declaration in the default ASPBE import surface; its kind and displayed Lean type determine how it may be used.

Technical source note. The source declaration has no docstring. The reader cue above is generated from its kind and name and does not replace the Lean signature.

Theorem6.25.4

uses 0used by 0✓L∃∀N

Plain-English reading. Lean checks the proposition indexed as “ccx basis action involutive”; the hypotheses and conclusion in the code panel fix its exact scope.

Formal status. Compiled theorem in the default ASPBE import surface; the displayed Lean signature is the authoritative claim.

Technical source note. The source declaration has no docstring. The reader cue above is generated from its kind and name and does not replace the Lean signature.

Declaration kind. theorem.
