Let $\mathcal{N}_0$ and $\mathcal{N}_1$ be quantum channels. In sequential channel discrimination, allow adaptive strategies that apply quantum instruments to the channel outputs a…

Unamortized-divergence conjecture. The various channel divergences without amortization should characterize the asymptotic error exponents of interest, as they do in the classical…

Consider the quantum channel discrimination problem described above, with lower and upper bounds for its exact strong converse exponent given in equations referenced as and. Strong…
