Quantum cryptography exploits principles of quantum physics for the secure processing of
information. A prominent example is secure communication, ie, the task of transmitting …

Random numbers are a fundamental resource in science and engineering with important
applications in simulation and cryptography. The inherent randomness at the core 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 …

Quantum Information Theory is an area of physics which studies both fundamental and
applied issues in quantum mechanics from an information-theoretical viewpoint. The …

Quantum state discrimination underlies various applications in quantum information
processing tasks. It essentially describes the distinguishability of quantum systems in …

VI Preface methods from information theory. Unconditionally secure schemes are now
addressed in an extra chapter, Chapter 10.• Unconditional security is not achievable without …

Randomness is an important resource for many applications, from gambling to secure
communication. However, guaranteeing that the output from a candidate random source …

We analyze the asymptotic security of the family of Gaussian modulated quantum key
distribution protocols for continuous-variables systems. We prove that the Gaussian unitary …

This thesis consolidates, improves and extends the smooth entropy framework for non-
asymptotic information theory and cryptography. We investigate the conditional min-and max …

The Leftover Hash Lemma states that the output of a two-universal hash function applied to
an input with sufficiently high entropy is almost uniformly random. In its standard formulation …
