marginal_counts(result, indices=None, inplace=False, format_marginal=False)¶
Marginalize counts from an experiment over some indices of interest.
result (dict or Result) – result to be marginalized (a Result object or a dict(str, int) of counts).
indices (list(int) or None) – The bit positions of interest to marginalize over. If
None(default), do not marginalize at all.
inplace (bool) – Default: False. Operates on the original Result argument if True, leading to loss of original Job Result. It has no effect if
resultis a dict.
format_marginal (bool) – Default: False. If True, takes the output of marginalize and formats it with placeholders between cregs and for non-indices.
- A Result object or a dictionary with
the observed counts, marginalized to only account for frequency of observations of bits of interest.
- Return type
Result or dict(str, int)
QiskitError – in case of invalid indices to marginalize over.
