qiskit.transpiler.passes.Commuting2qGateRouter.swap_decompose

Commuting2qGateRouter.swap_decompose(dag, node, current_layout, swap_strategy)

Take an instance of Commuting2qBlock and map it to the coupling map.

The mapping is done with the swap strategy.

Parámetros

• dag (DAGCircuit) – The dag which contains the Commuting2qBlock we route.

• node (DAGOpNode) – A node whose operation is a Commuting2qBlock.

• current_layout (Layout) – The layout before the swaps are applied. This function will modify the layout so that subsequent gates can be properly composed on the dag.

• swap_strategy (SwapStrategy) – The swap strategy used to decompose the node.

Devuelve

A dag that is compatible with the coupling map where swap gates have been added to map the gates in the Commuting2qBlock to the hardware.
