pygsti.report.direct_mc2gst_gatesets(gateStrings, dataset, specs, targetGateset, svdTruncateTo=0, minProbClipForWeighting=0.0001, probClipInterval=(-1000000.0, 1000000.0), verbosity=0)

Constructs a dictionary with keys == gate strings and values == Direct-LSGST GateSets.

Parameters:
  • gateStrings (list of GateString or tuple objects) – The gate strings to estimate using LSGST. The elements of this list are the keys of the returned dictionary.
  • dataset (DataSet) – The data to use for all LGST and LSGST estimates.
  • specs (2-tuple) – A (prepSpecs,effectSpecs) tuple usually generated by calling build_spam_specs(...)
  • targetGateset (GateSet) – The target gate set used by LGST to extract gate labels and an initial gauge
  • svdTruncateTo (int, optional) – The Hilbert space dimension to truncate the gate matrices to using a SVD to keep only the largest svdToTruncateTo singular values of the I_tildle LGST matrix. Defaults to no truncation.
  • minProbClipForWeighting (float, optional) – defines the clipping interval for the statistical weight used within the chi^2 function (see chi2fn).
  • probClipInterval (2-tuple, optional) – (min,max) to clip probabilities to within GateSet probability computation routines (see GateSet.bulk_fill_probs)
  • verbosity (int, optional) – Verbosity value to send to do_lgst(...) and do_mc2gst(...) calls.
Returns:

A dictionary that relates each gate string of gateStrings to a GateSet containing the LSGST estimate of that gate string stored under the gate label “GsigmaLbl”, along with LSGST estimates of the gates in targetGateset.

Return type:
