# AddTerminalRightDressedBoxes

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

[GitHub](https://github.com/Qiskit/samplomatic/tree/main/samplomatic/transpiler/passes/add_terminal_right_dressed_boxes.py#L69-L208)

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

Add right-dressed boxes to collect uncollected virtual gates emitted by left-dressed boxes.

> **Note**
>
> All boxes added by this pass are empty, so consider combining this pass with [`AbsorbSingleQubitGates`](/docs/api/samplomatic/auto/transpiler-passes-absorb-single-qubit-gates "samplomatic.transpiler.passes.AbsorbSingleQubitGates") if you would like nearby single-qubit gates to be placed into the boxes this pass adds.

**Parameters**

- **group** – The group to use for the box.
- **decomposition** – The decomposition to use for the box.
