qiskit.aqua.operators.converters.DictToCircuitSum

class DictToCircuitSum(traverse=True, convert_dicts=True, convert_vectors=True)

Converts DictStateFns or VectorStateFns to equivalent CircuitStateFns or sums thereof. The behavior of this class can be mostly replicated by calling to_circuit_op on an Operator, but with the added control of choosing whether to convert only DictStateFns or VectorStateFns, rather than both.

Parameters

• traverse (bool) – Whether to recurse down into Operators with internal sub-operators for conversion.

• convert_dicts (bool) – Whether to convert VectorStateFn.

• convert_vectors (bool) – Whether to convert DictStateFns.

__init__(traverse=True, convert_dicts=True, convert_vectors=True)

Parameters

• traverse (bool) – Whether to recurse down into Operators with internal sub-operators for conversion.

• convert_dicts (bool) – Whether to convert VectorStateFn.

• convert_vectors (bool) – Whether to convert DictStateFns.

Methods

__init__([traverse, convert_dicts, …])	type traverse bool
convert(operator)	Convert the Operator to CircuitStateFns, recursively if traverse is True.

convert(operator)

Convert the Operator to CircuitStateFns, recursively if traverse is True.

Parameters

operator (OperatorBase) – The Operator to convert

Return type

OperatorBase

Returns

The converted Operator.
