circuit_knitting_toolbox.circuit_cutting.wire_cutting.build

build(summation_terms, subcircuit_entry_probs, num_cuts, num_threads)[source]

Reconstruct the full probability distribution from the subcircuits.

Parameters:

  • summation_terms (-) – the summation terms used to generate the full vector, as generated in generate_summation_terms

  • subcircuit_entry_probs (-) – the probabilities vectors from the subcircuit executions

  • num_cuts (-) – the number of cuts

  • num_threads (-) – the number of threads to use for multithreading

Return type:

Tuple[NDArray, List[int], Dict[str, int]]

Returns:

a tuple containing:

  • (NDArray): the reconstructed probability distribution of the full circuit

  • (list): the ordering of the distribution

  • (dict): the computational post-processing overhead
