graphix_perceval.converter.pattern2graphstate(pattern: Pattern) → tuple[graphix.graphsim.GraphState, dict[int, float], list[int]][source]

Create a graph state from a MBQC pattern.

Parameters

pattern (graphix.Pattern object) – MBQC pattern to be run on the device

Returns

  • graph_state (graphix.GraphState object) – Graph state corresponding to the pattern.

  • phasedict (dict) – Dictionary of phases for each node.

  • output_nodes (list) – List of output nodes.

graphix_perceval.converter.to_perceval(pattern: Pattern) → PercevalExperiment[source]

Convert a graphix.Pattern to a perceval.Circuit.

Parameters

pattern (graphix.Pattern) – GraphState to be converted to a perceval.Circuit

Returns

experiment – graphix_perceval.experiment.PercevalExperiment object

Return type

PercevalExperiment

class graphix_perceval.converter.PercevalCircuitConstructor[source]
__init__()[source]
add_fusions() → None[source]

Find edges that connects two ResourceGraphs. If the two ResourceGraphs share a same node id, then they are fused. Type-1 fusion.
