qiskit.transpiler.CouplingMap.from_heavy_hex

classmethod CouplingMap.from_heavy_hex(distance, bidirectional=True)

Return a heavy hexagon graph coupling map.

A heavy hexagon graph is described in:

https://journals.aps.org/prx/abstract/10.1103/PhysRevX.10.011022

パラメータ

• distance (int) – The code distance for the generated heavy hex graph. The value for distance can be any odd positive integer. The distance relates to the number of qubits by: \(n = \frac{5d^2 - 2d - 1}{2}\) 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
