dwave.system.coupling_groups.coupling_groups

coupling_groups(hardware_graph)

Generate groups of couplers for which a limit on total coupling applies for each group.

Parameters:

hardware_graph (networkx.Graph) – The hardware graph of a QPU. Note that only Zephyr graphs have coupling groups.

Yields:

Lists of tuples, where each list is a group of couplers in hardware_graph.

Examples

This example prints the first coupling group of an Advantage2 QPU.

>>> from dwave.system.coupling_groups import coupling_groups
>>> from dwave.system import DWaveSampler
...
>>> qpu = DWaveSampler(solver=dict(topology__type='zephyr'))
>>> couplings = coupling_groups(qpu.to_networkx_graph())
>>> print(next(couplings)) 
[(1, 0), (12, 0), (2496, 0), (2520, 0), (2544, 0), (2568, 0)]
