Quantizing Time
Whatever the final theory of quantum gravity turns out to be, it will need to reconcile the incongruent ways in which time appears in quantum mechanics and general relativity. Quantum...

Quantum Gravity 2020
The conference “Quantum Gravity 2020" has a deliberately broad scope. We aim to include participants from all current approaches to quantum gravity, as well as researchers working on the phenomenology...

Indefinite Causal Structure
There has been a surge of interest in indefinite causal structure, the idea that cause and effect can no longer be sharply distinguished. Motivated both by experimentation with quantum switches...

Observers in Quantum and Foil Theories
Foil theories sometimes called mathematically rigorous science fiction describe ways the world could have been were it not quantum mechanical. Our understanding of quantum theory has been deepened by contrasting...

Algorithmic Information, Induction and Observers in Physics
Our universe is of astonishing simplicity: almost all physical observations can in principle be described by a few theories that have short mathematical descriptions. But there is a field of...

Experimental Quantum Foundations
Our understanding of the ways in which quantum theory represents a conceptual innovation relative to classical physics – and of the experimental signatures of such nonclassicality – continues to improve...

Contextuality: Conceptual Issues, Operational Signatures, and Applications
2017 marks 50 years since the seminal 1967 article of Kochen and Specker proving that quantum theory fails to admit of a noncontextual model. Despite the fact that the Kochen-Specker...

Hopf Algebras in Kitaev's Quantum Double Models: Mathematical Connections from Gauge Theory to Topological Quantum Computing and Categorical Quantum Mechanics
The Kitaev quantum double models are a family of topologically ordered spin models originally proposed to exploit the novel condensed matter phenomenology of topological phases for fault-tolerant quantum computation. Their...

Information Theoretic Foundations for Physics
In the last few decades, there has been a growing consensus that information theory is of fundamental importance for theoretical physics. The information paradigm has yielded successes in many different...
