Analytic Rényi Entropy Bounds for Device-Independent Cryptography
Thomas A. Hahn, Aby Philip, Ernest Y. -Z. Tan +1
Device-independent (DI) cryptography represents the highest level of security, enabling cryptographic primitives to be executed safely on uncharacterized devices. Moreover, with su…

Marginal-constrained entropy accumulation theorem
Amir Arqand, Ernest Y. -Z. Tan
We derive a novel chain rule for a family of channel conditional entropies, covering von Neumann and sandwiched Rényi entropies. In the process, we show that these channel conditio…
