pygsti.tools.sums_of_negative_choi_evals(gateset)

Compute the amount of non-CP-ness of a gateset by summing the negative eigenvalues of the Choi matrix for each gate in gateset separately.

Parameters:gateset (GateSet) – The gate set to act on.
Returns:each element == sum of the negative eigenvalues of the Choi matrix for the corresponding gate (as ordered by gateset.gates.iteritems()).
Return type:list of floats
