Base Fields

HilbertBaseField defines how the mathematics of HilbertArray works. Normally you don’t need to worry about this because usually the default implementation is appropriate. It is not recommened to call the constructor directly. Instead, use the interface provided by qitensor.factory.base_field_lookup(), or just use the dtype parameter of the factory functions in qitensor.factory. A subclass, SageHilbertBaseField, provides the ability to create arrays over Sage types (e.g. SR). This, too, is accessed through base_field_lookup or by passing the dtype parameter.
