iqm.benchmarks.entanglement.ghz_optimal.cx_pairs(direct_ghz: IQMCircuit, order: Sequence[int]) → list[tuple[int, int]]

Recover the physical-index CX pairs of a generated GHZ circuit, in circuit order.

Parameters:

• direct_ghz (IQMCircuit) – A circuit built by generate_ghz_tree_optimal().

• order (Sequence[int]) – The physical qubits in logical-qubit order, as returned alongside it.

Returns:

The (control, target) pairs as physical qubit indices.

Return type:

list[tuple[int, int]]
