probability_matrix
(gateString, gateset, spamlabel, strs, fidPairs=None)¶ Computes spamLabel’s probability matrix for a base gatestring.
Parameters: - gateString (tuple of gate labels) – The gate sequence that is sandwiched between each effectStr and prepStr
- gateset (GateSet) – The gate set used to specify the probabilities
- spamLabel (string) – The spam label to extract probabilities for, e.g. ‘plus’
- strs (2-tuple) – A (prepStrs,effectStrs) tuple usually generated by calling get_spam_strs(...)
- fidPairs (list, optional) – A list of (iRhoStr,iEStr) tuples specifying a subset of all the prepStr,effectStr pairs to include in the matrix. Other values are set to NaN.
Returns: probability values corresponding to spamLabel and gate sequences where gateString is sandwiched between the each (effectStr,prepStr) pair.
Return type: numpy array of shape ( len(effectStrs), len(prepStrs) )
