Constructor Theory of Information with Dr Chiara Marletto
What if we don't need quantum mechanics to express the key properties of quantum information? Join me for a deep-dive into the Constructor Theory of information with Dr Chiara Marletto, Research Fellow at the University of Oxford.
Constructor Theory is a research programme proposed by Prof. David Deutsch in 2012, and further developed by Deutsch and Marletto, and collaborators, since then. The theory aims to unify various strands of physics, and solve open problems — and the key motivation and starting point is a new conception of the laws of physics surrounding information.
In this podcast, we discuss what constructor theory is; how it expresses laws about classical and quantum information; applications to e.g. tests of quantum gravity and quantum field theory; the role of locality and subsystems in the testability of physics; and taking fundamental physics back to the roots of the early days of quantum information theory.

Testing Quantum Gravity & Reality with Prof. Vlatko Vedral
In this episode of the Quantum Foundations Podcast, I'm joined by Professor Vlatko Vedral from the University of Oxford. We discuss modern and historic experimental proposals for testing quantum gravity. Get ready to dive deep into understanding what different proposals would *really* tell us about the nature of quantum gravity, and what problems we're up against to reconcile quantum mechanics and general relativity. All from the modern perspective of quantum information theory.

QBism, Relational QM & Wigner's Friend with Dr Andrea Di Biagio
I interview Dr Andrea Di Biagio, who is a postdoctoral research fellow at IQOQI Vienna. We discuss Andrea's journey through interpretations of quantum theory, including QBism, Relational Quantum Mechanics, Everettian Quantum Theory and Wigner's friend. These topics have been subjects of Andrea's past and active research, including work with Prof. Carlo Rovelli.

Everettian Quantum Theory with Dr Sam Kuypers
I interview Dr Sam Kuypers, who is a postdoctoral research fellow at the Université de Montréal. We discuss the many-worlds interpretation of quantum mechanics, also known as Everettian quantum theory, which has been the subject of Sam's research including work together with Prof. David Deutsch.

Does quantum reality emerge from causation? Feat. Dr Nick Ormrod
I interview Dr Nick Ormrod, who recently completed his DPhil at the University of Oxford and is now a post-doctoral research fellow at the Perimeter Institute in Canada. We discuss the new interpretation of quantum theory that Nick has been working on during his DPhil, with Prof. Jonathan Barrett. The key idea is that reality emerges from causal structures.
What does quantum physics tell us about reality? What progress have we made since the days of Einstein and Schrödinger, and what problems are today’s quantum research scientists trying to solve? This podcast aims to share a modern perspective on the most fundamental aspects of quantum theory, informed by up-to-date research insights. In each episode, I interview an active researcher about a topic related to their work, with the discussion aimed to be broadly accessible.
