qiskit.transpiler.CouplingMap.from_heavy_square

classmethod CouplingMap.from_heavy_square(distance, bidirectional=True)

Return a heavy square graph coupling map.

A heavy square graph is described in:

매개변수

• distance (int) – The code distance for the generated heavy square graph. The value for distance can be any odd positive integer. The distance relates to the number of qubits by: \(n = 3d^2 - 2d\) where \(n\) is the number of qubits and \(d\) is the distance parameter.

• bidirectional (bool) – Whether the edges in the output coupling graph are bidirectional or not. By default this is set to True
