# SamplingMinimumEigensolver

*class* `qiskit.algorithms.minimum_eigensolvers.SamplingMinimumEigensolver`

[GitHub](https://github.com/qiskit/qiskit/tree/stable/0.46/qiskit/algorithms/minimum_eigensolvers/sampling_mes.py)

Bases: [`ABC`](https://docs.python.org/3/library/abc.html#abc.ABC)

The Sampling Minimum Eigensolver Interface.

## Methods

### compute\_minimum\_eigenvalue

*abstract* `compute_minimum_eigenvalue(operator, aux_operators=None)`

Compute the minimum eigenvalue of a diagonal operator.

**Parameters**

- **operator** (*BaseOperator |* [*PauliSumOp*](/docs/api/qiskit/0.46/qiskit.opflow.primitive_ops.PauliSumOp "qiskit.opflow.primitive_ops.PauliSumOp")) – Diagonal qubit operator.
- **aux\_operators** (*ListOrDict\[BaseOperator |* [*PauliSumOp*](/docs/api/qiskit/0.46/qiskit.opflow.primitive_ops.PauliSumOp "qiskit.opflow.primitive_ops.PauliSumOp")*] | None*) – Optional list of auxiliary operators to be evaluated with the final state.

**Returns**

A [`SamplingMinimumEigensolverResult`](/docs/api/qiskit/0.46/qiskit.algorithms.minimum_eigensolvers.SamplingMinimumEigensolverResult "qiskit.algorithms.minimum_eigensolvers.SamplingMinimumEigensolverResult") containing the optimization result.

**Return type**

[SamplingMinimumEigensolverResult](/docs/api/qiskit/0.46/qiskit.algorithms.minimum_eigensolvers.SamplingMinimumEigensolverResult "qiskit.algorithms.minimum_eigensolvers.SamplingMinimumEigensolverResult")

### supports\_aux\_operators

*classmethod* `supports_aux_operators()`

Whether computing the expectation value of auxiliary operators is supported.

If the minimum eigensolver computes an eigenstate of the main operator then it can compute the expectation value of the aux\_operators for that state. Otherwise they will be ignored.

**Returns**

True if aux\_operator expectations can be evaluated, False otherwise

**Return type**

[bool](https://docs.python.org/3/library/functions.html#bool)
