# DictToCircuitSum

*class* `qiskit.opflow.converters.DictToCircuitSum(traverse=True, convert_dicts=True, convert_vectors=True)`

[GitHub](https://github.com/qiskit/qiskit/tree/stable/0.46/qiskit/opflow/converters/dict_to_circuit_sum.py)

Bases: [`ConverterBase`](/docs/api/qiskit/0.46/qiskit.opflow.converters.ConverterBase "qiskit.opflow.converters.converter_base.ConverterBase")

Deprecated: 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.

> **Deprecated since version 0.24.0**
>
> The class `qiskit.opflow.converters.dict_to_circuit_sum.DictToCircuitSum` is deprecated as of qiskit-terra 0.24.0. It will be removed in the Qiskit 1.0 release. For code migration guidelines, visit [https://qisk.it/opflow\_migration](https://qisk.it/opflow_migration).

**Parameters**

- **traverse** ([*bool*](https://docs.python.org/3/library/functions.html#bool)) – Whether to recurse down into Operators with internal sub-operators for conversion.
- **convert\_dicts** ([*bool*](https://docs.python.org/3/library/functions.html#bool)) – Whether to convert VectorStateFn.
- **convert\_vectors** ([*bool*](https://docs.python.org/3/library/functions.html#bool)) – Whether to convert DictStateFns.

## Methods

### convert

`convert(operator)`

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

**Parameters**

**operator** ([*OperatorBase*](/docs/api/qiskit/0.46/qiskit.opflow.OperatorBase "qiskit.opflow.operator_base.OperatorBase")) – The Operator to convert

**Returns**

The converted Operator.

**Return type**
