Purity and computational-basis coherence

Exact diagnostic and entanglement identities › Purity and computational-basis coherence · lines 561–570

Use the specified normalized diagnostic

C_{ℓ_{1}}^{norm} (ρ) = \frac{\sum _{x \neq = y} ∣ ρ _{x y} ∣}{2 ^{N} - 1} .

Its numerator is the usual basis-dependent $ℓ_{1}$ coherence BCP; the denominator is an additional convention.
