- VectorStateFn.primitive_strings()[source]¶
Return a set of strings describing the primitives contained in the Operator. For example,
{'QuantumCircuit', 'Pauli'}. For hierarchical Operators, such asListOps, this can help illuminate the primitives represented in the various recursive levels, and therefore which conversions can be applied.- Returns
