qpu_graph(topology_type, topology_shape, nodelist, edgelist)[source]#

Convert node and edge lists to a dwave-graphs graph.

Creates a QPU topology (Chimera, Pegasus or Zephyr) graph compatible with Ocean software’s dwave-graphs.

Parameters:

  • topology_type (string) – Type of lattice. Valid strings are 'chimera', 'pegasus' and 'zephyr'.

  • topology_shape (iterable of ints) – Dimensions of the lattice.

  • nodelist (list of ints) – List of nodes in the graph. Node labeling is integer and compatible with the linear labeling scheme for the specified topology_type.

  • edgelist (list of Tuples) – List of edges in the graph, with each edge consisting of a pair of nodes.
