A further generalization and refinement of these results due to Samson Abramsky, Rui Soares Barbosa and Shane Mansfield appeared in 2017, proving a precise quantifiable relationship between the probability of successfully computing any given non-linear function and the degree of contextuality present in the l2 -MBQC as measured by the contextual fraction. Specifically, ( 1 − − p s ) ≥ ≥ ( 1 − − C F ( e ) ) . ν ν ( f ) where p s , C F ( e ) , ν ν ( f ) ∈ ∈ [ 0 , 1 ] are the probability of success, the contextual fraction of the measurement statistics e, and a measure of the non-linearity of the function to be computed f , respectively.
