resolve(registry: ext.ExtensionRegistry) → Type¶: Resolve types in the type using the given registry.

to_model() → Term[source]¶: Convert the type to a model Term.

type_arg() → TypeTypeArg¶

The TypeTypeArg for this type.

Example

>>> Qubit.type_arg()
TypeTypeArg(ty=Qubit)

type_bound() → TypeBound[source]¶

The bound of this type.

Example

>>> Tuple(Bool, Bool).type_bound()
TypeBound.Copyable
>>> Tuple(Qubit, Bool).type_bound()
TypeBound.Linear
