We show that quantum-to-classical channels, ie, quantum measurements, can be
asymptotically simulated by an amount of classical communication equal to the quantum …

We study non-asymptotic fundamental limits for transmitting classical information over
memoryless quantum channels, ie we investigate the amount of classical information that …

We consider the problem of communication over a classical-quantum broadcast channel
with one sender and two receivers. Generalizing the classical inner bounds shown by …

Quantum generalizations of Rényi's entropies are a useful tool to describe a variety of
operational tasks in quantum information processing. Two families of such generalizations …

Quantum error correction (QEC) is one of the central concepts in quantum information
science and also has wide applications in fundamental physics. The capacity theorems …

We introduce a task that we call partial decoupling, in which a bipartite quantum state is
transformed by a unitary operation on one of the two subsystems and then is subject to the …

We consider sets of trace‐normalized non‐negative operators in Hilbert–Schmidt balls that
maximize their mutual Hilbert–Schmidt distance; these are optimal arrangements in the sets …

Quantum-proof randomness extractors are an important building block for classical and
quantum cryptography as well as device independent randomness amplification and …

We address the question of efficient implementation of quantum protocols, with small
communication and entanglement, and short depth circuit for encoding or decoding. We …

In Hall's reformulation of the uncertainty principle, the entropic uncertainty relation occupies
a core position and provides the first nontrivial bound for the information exclusion principle …
