Approximate Degradable Quantum Channels
David Sutter, Volkher B. Scholz, Andreas Winter +1
Degradable quantum channels are an important class of completely positive trace-preserving maps. Among other properties, they offer a single-letter formula for the quantum and the…
Quantum-proof randomness extractors via operator space theory
Mario Berta, Omar Fawzi, Volkher B. Scholz
Quantum-proof randomness extractors are an important building block for classical and quantum cryptography as well as device independent randomness amplification and expansion. Fur…
Many-body localisation implies that eigenvectors are matrix-product states
M. Friesdorf, A. H. Werner, W. Brown +2
The phenomenon of many-body localisation received a lot of attention recently, both for its implications in condensed-matter physics of allowing systems to be an insulator even at…
Operationally-Motivated Uncertainty Relations for Joint Measurability and the Error-Disturbance Tradeoff
Joseph M. Renes, Volkher B. Scholz
We derive new Heisenberg-type uncertainty relations for both joint measurability and the error-disturbance tradeoff for arbitrary observables of finite-dimensional systems. The rel…
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…
