Sequential Quantum Channel Discrimination
Yonglong Li, Christoph Hirche, Marco Tomamichel
We consider the sequential quantum channel discrimination problem using adaptive and non-adaptive strategies. In this setting the number of uses of the underlying quantum channel i…
Ultimate limits for quickest quantum change-point detection
Marco Fanizza, Christoph Hirche, John Calsamiglia
Detecting abrupt changes in data streams is crucial because they are often triggered by events that have important consequences if left unattended. Quickest change point detection…
Bounding quantum capacities via partial orders and complementarity
Christoph Hirche, Felix Leditzky
Quantum capacities are fundamental quantities that are notoriously hard to compute and can exhibit surprising properties such as superadditivity. Thus, a vast amount of literature…
Quantum Differential Privacy: An Information Theory Perspective
Christoph Hirche, Cambyse Rouzé, Daniel Stilck França
Differential privacy has been an exceptionally successful concept when it comes to providing provable security guarantees for classical computations. More recently, the concept was…
