# AddNoops

*class* `samplomatic.transpiler.passes.insert_noops.AddNoops(*args, **kwargs)`

[GitHub](https://github.com/Qiskit/samplomatic/tree/main/samplomatic/transpiler/passes/insert_noops/add_noops.py#L23-L79)

Bases: [`TransformationPass`](/docs/api/qiskit/qiskit.transpiler.TransformationPass)

Expand boxes to the given `qubits`.

This pass leaves non-box operations as-is, but boxes are modified to span the original qubits, original clbits, and any user-specified qubits not already included in the original qubits.
