Quantum mechanics and information theory are among the most important scientific discoveries of the last century. Although these two areas initially developed separately, it has emerged that they are in fact intimately related. In this review the author shows how quantum information theory extends traditional information theory by exploring the limits imposed by quantum, rather than classical, mechanics on information storage and transmission. The derivation of many key results differentiates… 
Measures and applications of quantum correlations
This work gives an overview of the current quest for a proper understanding and characterisation of the frontier between classical and quantum correlations (QCs) in composite states, and focuses on various approaches to define and quantify general QCs, based on different yet interlinked physical perspectives.
Foundations of quantum theory and quantum information applications
This thesis establishes a number of connections between foundational issues in quantum theory, and some quantum information applications. It starts with a review of quantum contextuality and
We provide a historical perspective of how the notion of correlations has evolved within quantum physics. We begin by reviewing Shannon's information theory and its first application in quantum
Some Theory and Applications of Probability in Quantum Mechanics
It is proved that quantum states are more difficult to estimate than their classical counterparts by finding optimal estimation strategies, requiring the solution to a difficult optimization problem, are difficult to implement in practise.
Bounding generalized relative entropies: Nonasymptotic quantum speed limits.
By considering a general unitary channel, this work establishes a bound on the generalized relative entropies (Rényi and Tsallis) between the output and the input of the channel, and derives a family of quantum speed limits based on relative entropy.
The classical-quantum boundary for correlations: Discord and related measures
One of the best signatures of nonclassicality in a quantum system is the existence of correlations that have no classical counterpart. Different methods for quantifying the quantum and classical
Preamble Probability Density Operators Spectral Theorem Postscript Introduction to quantum information processing Measurements and quantum probability
The topic of these lectures lies in the new and rapidly growing field of quantum computing, which explores connections between physics and computing in general and deepened understanding of the relationship between physics, information and computation in general.
Resource theories of quantum coherence: foundations and applications
This thesis concentrates on understanding quantum coherence in the mathematical framework of resource theories, viewing it both as a resource to be harnessed and as a way to quantitatively characterise quantum states in contrast to classical states.
Relative entropy between quantum ensembles
This paper proposes a notion of relative entropy between quantum ensembles, which is a natural generalization of the relative entropyBetween quantum states, and demonstrates that a set consisting of two pure states is the most quantum when the states are 45° apart.
The classification and quantification of correlations (classical and quantum) in composite quantum systems are of fundamental significance for quantum information processing. While the paradigm of


Distinguishability and Accessible Information in Quantum Theory
This document focuses on translating various information-theoretic measures of distinguishability for probability distributions into measures of distin- guishability for quantum states, and gives a way of expressing the problem so that it appears as algebraic as that of the problem of finding quantum distinguishability measures.
Mathematical Foundations of Quantum Mechanics
Mathematical Foundations of Quantum Mechanics was a revolutionary book that caused a sea change in theoretical physics. Here, John von Neumann, one of the leading mathematicians of the twentieth
Separability and distillability in composite quantum systems-a primer
This article presents a primer on the current state of knowledge concerning two problems of quantum information theory, and discusses the relation of these problems to one of the most challenging questions of linear algebra: the classification and characterization of positive operator maps.

Relative entropy in quantum information theory
The properties of the quantum relative entropy function are reviewed and its application to problems of classical and quantum information transfer and to quantum data compression is discussed.
A fast quantum mechanical algorithm for database search
In early 1994, it was demonstrated that a quantum mechanical computer could efficiently solve a well-known problem for which there was no known efficient algorithm using classical computers, i.e. testing whether or not a given integer, N, is prime, in a time which is a finite power of o (logN) .
Quantum lower bounds by polynomials
This work examines the number T of queries that a quantum network requires to compute several Boolean functions on {0,1}/sup N/ in the black-box model and gives asymptotically tight characterizations of T for all symmetric f in the exact, zero-error, and bounded-error settings.

Quantum lower bounds by quantum arguments
Two new Ω(√N) lower bounds on computing AND of ORs and inverting a permutation and more uniform proofs for several known lower bounds which have been previously proven via a variety of different techniques are proved.
