- class VectorStateFn(primitive=None, coeff=1.0, is_measurement=False)¶
A class for state functions and measurements which are defined in vector representation, and stored using Terra’s
None]) – The
Statevector, NumPy array, or list, which defines the behavior of the underlying function.
ParameterExpression]) – A coefficient multiplying the state function.
bool) – Whether the StateFn is a measurement operator
