# BMSynthesisClifford

*class* `qiskit.transpiler.passes.synthesis.hls_plugins.BMSynthesisClifford`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.3/qiskit/transpiler/passes/synthesis/hls_plugins.py#L512-L532)

Bases: [`HighLevelSynthesisPlugin`](/docs/api/qiskit/1.3/qiskit.transpiler.passes.synthesis.plugin.HighLevelSynthesisPlugin "qiskit.transpiler.passes.synthesis.plugin.HighLevelSynthesisPlugin")

Clifford synthesis plugin based on the Bravyi-Maslov method.

The method only works on Cliffords with at most 3 qubits, for which it constructs the optimal CX cost decomposition.

This plugin name is :`clifford.bm` which can be used as the key on an [`HLSConfig`](/docs/api/qiskit/1.3/qiskit.transpiler.passes.HLSConfig "qiskit.transpiler.passes.HLSConfig") object to use this method with [`HighLevelSynthesis`](/docs/api/qiskit/1.3/qiskit.transpiler.passes.HighLevelSynthesis "qiskit.transpiler.passes.HighLevelSynthesis").

## Methods

### run

`run(high_level_object, coupling_map=None, target=None, qubits=None, **options)`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.3/qiskit/transpiler/passes/synthesis/hls_plugins.py#L522-L532)

Run synthesis for the given Clifford.
