35. Further invariants are required to specify the full ring of invariants under LU transformations.
36. The statistical inference theory used in this section can be found in many statistics textbooks, such as Ref. [33].
37. However, since this work first appeared it has been shown [34] that the SLOCC invariants can be estimated without the need for introducing noise and circuits have been explicitly constructed for the concurrence and 3-tangle. The statistical efficiency of these circuits has not yet been analyzed.
