quant-ph2026

Sharp continuity of quantum conditional entropy

Mario Berta, Pablo Costa Rico, Gereon Kossmann +2

We prove the sharp uniform continuity bound for quantum conditional entropy. If two bipartite states are at trace distance at most I^´ and d=dimA, the optimal dimension-only m…

quant-ph2026

Routed Bell tests with arbitrarily many local parties

Gereon Koßmann, Mario Berta, René Schwonnek

Device-independent quantum key distribution (DIQKD) promises cryptographic security based solely on observed quantum correlations, yet its implementation over long distances remain…

quant-ph2025

On approximate quantum error correction for symmetric noise

Gereon Koßmann, Julius A. Zeiss, Omar Fawzi +1

We revisit the extendability-based semi-definite programming hierarchy introduced by Berta et al. [Mathematical Programming, 1 - 49 (2021)], which provides converging outer bounds…

quant-ph2025

Approximating fixed size quantum correlations in polynomial time

Julius A. Zeiss, Gereon Koßmann, Gereon Koßmann +2

We show that ε-additive approximations of the optimal value of fixed-size two-player free games with fixed-dimensional entanglement assistance can be computed in time $…
