Variations on Classical and Quantum Extractors
Mario Berta, Omar Fawzi, Volkher B. Scholz +1
Many constructions of randomness extractors are known to work in the presence of quantum side information, but there also exist extractors which do not [Gavinsky {\it et al.}, STOC…
On quantum Renyi entropies: a new generalization and some properties
Martin Müller-Lennert, Frédéric Dupuis, Oleg Szehr +2
The Renyi entropies constitute a family of information measures that generalizes the well-known Shannon entropy, inheriting many of its properties. They appear in the form of uncon…
Decoupling Theorems
Oleg Szehr
Decoupling theorems have proven useful in various applications in the area of quantum information theory. This thesis builds upon preceding work by Frédéric Dupuis [arXiv:1012.6044…
A decoupling approach to classical data transmission over quantum channels
Frédéric Dupuis, Oleg Szehr, Marco Tomamichel
Most coding theorems in quantum Shannon theory can be proven using the decoupling technique: to send data through a channel, one guarantees that the environment gets no information…
Decoupling with unitary approximate two-designs
Oleg Szehr, Frédéric Dupuis, Marco Tomamichel +1
Consider a bipartite system, of which one subsystem, A, undergoes a physical evolution separated from the other subsystem, R. One may ask under which conditions this evolution dest…
