draw_chimera_embedding(G, *args, **kwargs)[source]#

Draws an embedding onto the Chimera graph G.

Parameters:

  • G (NetworkX graph) – Chimera graph or a subgraph of a Chimera graph.

  • emb (dict) – Embedding for all nodes of G as a dict of chains of the form {node: chain, ...}. where chains are iterables of qubit labels. Qubits are nodes in G.

  • embedded_graph (NetworkX graph (optional, default None)) – Graph which contains all keys of the emb parameter as nodes. If specified, the edges of G are considered to be interactions if and only if they exist between two chains of the emb parameter and if their keys are connected by an edge in the embedded_graph parameter; only the couplers for edges of G that are considered to be interactions are displayed.

  • interaction_edges (list (optional, default None)) – Interactions as a list of edges. If this parameter is specified, only the couplers in the list are displayed.

  • show_labels (boolean (optional, default False)) – If True, each chain in the emb parameter is labelled with its key.

  • chain_color (dict (optional, default None)) – Chain colors associated with each key in the emb parameter as a dict of the form {node: rgba_color, ...}, where colors must be length-4 tuples of floats between 0 and 1, inclusive. If None, each chain is assigned a different color.

  • unused_color (tuple (optional, default (0.9,0.9,0.9,1.0))) – Color to use for graph G’s nodes and edges that are not part of chains, and edges that are neither chain edges nor interactions. If None, these nodes and edges are not shown.

  • overlapped_embedding (boolean (optional, default False)) – If True, chains in the emb parameter may overlap (contain the same vertices in G), and the drawing displays these overlaps as concentric circles.

  • kwargs (optional keywords) – Parameters in draw_networkx(), except for the pos parameter. If the linear_biases or quadratic_biases parameters are specified, the draw_networkx() node_color or edge_color parameters are ignored.
