The complete deterministic and asymptotic comparison chain
OpenQAlgorithms.Papers.Independent.Intakethird100.P83.deterministicChainLet be any normalized finite-dimensional bipartite state. Let be its exact one-copy PPT rate with real target size, the supremum of its positive-blocklength exact rate ratios, the PPT rate with fidelity tending to one, the logarithm of SDP (7), and its logarithmic negativity. Then
All quantities are evaluated on the same state. The chain does not assert equality between deterministic and vanishing-error rates in general.

For any finite nonempty types , each with decidable equality, and any positive semidefinite complex matrix indexed by with trace , define , let , and let be the Euclidean operator norm. Define as the real supremum of subject to , , and , where means positive semidefinite difference. Define , , and , with no nonnegativity restriction on . Tensor powers have entries , with the zeroth power equal to the scalar . Finally, set , where is Hermitian, , and , and set ; all suprema here are real-valued. Then
