CouplingGraph.is_valid_coupling_graph

static CouplingGraph.is_valid_coupling_graph(coupling_graph, num_qudits=None)[source]

Return true if the coupling graph is valid.

Parameters:

coupling_graph (Any) – The coupling graph to check.
num_qudits (int | None) – The total number of qudits. All qudits should be less than this. If None, don’t check.

Returns:

Valid or not

Return type:

TypeGuard[Iterable[tuple[int, int]] | CouplingGraph]
