Value Indefiniteness, Randomness and Unpredictability in Quantum Foundations
The outcomes of quantum measurements are generally considered to be random, but despite the fact that this randomness is an important element in quantum information theory, its nature is not well understood. In this thesis, we study several issues relating to the origin and certification of quantum …

TOWARDS QUANTUM ADVANTAGE AND CERTIFICATION WITH NOISY INTERMEDIATE-SCALE QUANTUM DEVICES
The second quantum revolution’s success critically depends on the practical applications of the noisy intermediate-scale quantum devices. Despite the hope rendered by the experimental demonstration of “quantum supremacy”, the essential question regarding how to translate such breakthroughs into …

Quantum information, Bell inequalities and the no-signalling principle
… bound on the success probability of a class of quantum teleportation protocols, denoted as port-based teleportation, from the no-cloning theorem and the no-signalling principle. Chapter 4 introduces the principle of quantum information causality. Chapter 2 considers the predictions of quantum …

Relativistic Quantum Tasks
Quantum mechanics, which describes the behaviour of matter and energy on very small scales, is one of the most successful theories in the history of science. Einstein's theory of special relativity, which describes the relationship between space and time, is likewise a highly successful and widely …

Quantum theory from the perspective of general probabilistic theories
This thesis explores various perspectives on quantum phenomena, and how our understanding of these phenomena is informed by the study of general probabilistic theories. Particular attention is given to quantum nonlocality, and its interaction with areas of physical and mathematical interest such as …
