pygsti.tools.fidelity_upper_bound

pygsti.tools.fidelity_upper_bound(gateMx)
Get an upper bound on the fidelity of the given
gate matrix with any unitary gate matrix.
The closeness of the result to one tells
how “unitary” the action of gateMx is.
Parameters:gateMx (numpy array) – The gate matrix to act on.
Returns:The resulting upper bound on fidelity(gateMx, anyUnitaryGateMx)
Return type:float
