Efficient Quantum Measurements: Computational Max- and Measured Rényi Divergences and Applications
Álvaro Yángüez, Thomas A. Hahn, Jan Kochanowski
Quantum information processing is limited, in practice, to efficiently implementable operations. This motivates the study of quantum divergences that preserve their operational mea…

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…
