circuit_knitting.cutting.cutqc.build

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

Reconstruct the full probability distribution from the subcircuits.

Deprecated since version 0.7.0: The function circuit_knitting.cutting.cutqc.wire_cutting_post_processing.build() is deprecated as of circuit-knitting-toolbox 0.7.0. It will be removed no sooner than CKT v0.8.0. Use the wire cutting or automated cut-finding functionality in the circuit_knitting.cutting package.

Parameters:

  • summation_terms (Sequence[dict[int, int]]) – The summation terms used to generate the full vector, as generated in generate_summation_terms

  • subcircuit_entry_probs (dict[int, dict[int, ndarray]]) – The probabilities vectors from the subcircuit executions

  • num_cuts (int) – The number of cuts

  • num_threads (int) – The number of threads to use for multithreading

Return type:

tuple[ndarray, list[int], dict[str, int]]

Returns:

A tuple containing the reconstructed probability distribution of the full circuit, the ordering of the distribution, and the computational post-processing overhead
