The Physics of Quantum Information: Complementarity, Uncertainty, and Entanglement

TL;DR

This thesis explores how quantum complementarity underpins quantum information theory, clarifying its nature and aiding in the development of quantum information processing protocols.

Contribution

It demonstrates the central role of complementarity in understanding and constructing quantum information protocols, providing a unifying perspective.

Findings

Complementarity is fundamental to quantum information theory.

Understanding complementarity helps clarify what quantum information entails.

The research aids in designing quantum information processing protocols.

Abstract

The overarching goal of this thesis is to demonstrate that complementarity is at the heart of quantum information theory, that it allows us to make (some) sense of just what information "quantum information" refers to, and that it is useful in understanding and constructing quantum information processing protocols. The detailed research results which form the basis of these claims are to be found in the included papers, and the aim here is to present an overview comprehensible to a more general audience.
