# DefaultSynthesisClifford

*class* `qiskit.transpiler.passes.synthesis.high_level_synthesis.DefaultSynthesisClifford`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.2/qiskit/transpiler/passes/synthesis/high_level_synthesis.py#L724-L738)

Bases: [`HighLevelSynthesisPlugin`](/docs/api/qiskit/1.2/qiskit.transpiler.passes.synthesis.plugin.HighLevelSynthesisPlugin "qiskit.transpiler.passes.synthesis.plugin.HighLevelSynthesisPlugin")

The default clifford synthesis plugin.

For N \<= 3 qubits this is the optimal CX cost decomposition by Bravyi, Maslov. For N > 3 qubits this is done using the general non-optimal greedy compilation routine from reference by Bravyi, Hu, Maslov, Shaydulin.

This plugin name is :`clifford.default` which can be used as the key on an [`HLSConfig`](/docs/api/qiskit/1.2/qiskit.transpiler.passes.HLSConfig "qiskit.transpiler.passes.synthesis.high_level_synthesis.HLSConfig") object to use this method with [`HighLevelSynthesis`](/docs/api/qiskit/1.2/qiskit.transpiler.passes.HighLevelSynthesis "qiskit.transpiler.passes.synthesis.high_level_synthesis.HighLevelSynthesis").

## Methods

### run

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