Heisenberg's uncertainty principle forms a fundamental element of quantum mechanics.
Uncertainty relations in terms of entropies were initially proposed to deal with conceptual …

The Rényi 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 …

This book provides the reader with the mathematical framework required to fully explore the
potential of small quantum information processing devices. As decoherence will continue to …

A strong converse theorem for the classical capacity of a quantum channel states that the
probability of correctly decoding a classical message converges exponentially fast to zero in …

Quantum cryptography is the art and science of exploiting quantum mechanical effects in
order to perform cryptographic tasks. While the most well-known example of this discipline is …

We ask the question whether entropy accumulates, in the sense that the operationally
relevant total uncertainty about an n-partite system A=(A_1, ... A_n) A=(A 1,… A n) …

Recently, an entropic uncertainty relation for multiple measurements was proposed by Liu et
al.[Phys. Rev. A 91, 042133 (2015) 10.1103/PhysRevA. 91.042133]. However, the lower …
