Bounds on Petz-Rényi Divergences and their Applications for Device-Independent Cryptography
Thomas A. Hahn, Ernest Y. -Z. Tan, Peter Brown
Variational techniques have been recently developed to find tighter bounds on the von Neumann entropy in a completely device-independent (DI) setting. This, in turn, has led to sig…

Generalized Rényi entropy accumulation theorem and generalized quantum probability estimation
Amir Arqand, Thomas A. Hahn, Ernest Y. -Z. Tan
The entropy accumulation theorem, and its subsequent generalized version, is a powerful tool in the security analysis of many device-dependent and device-independent cryptography p…
