Quantum Foundations Podcast
Deriving probability in quantum many-worlds with Dr Tony Short
If there really is a quantum reality for every possible outcome of a measurement, then where do measurement probabilities come from? Dr Tony Short at the University of Bristol has used a set of intuitive assumptions to derive probability in a quantum multiverse. In this episode we discuss his motivations for exploring the many-worlds interpretation; what his assumptions are and how they lead to the Born rule for measurement probabilities; and how these ideas fit within the broader landscape of research in quantum foundations, probability and the many-worlds interpretation.

Solving nonlocality with fractals, chaos & counterfactuals | Prof. Tim Palmer
The notion of true quantum nonlocality is absurd. Prof Tim Palmer from the University of Oxford suggests that there is a hidden assumption in standard quantum mechanics, and dropping it will save us from this absurdity. Namely, the reality of counterfactuals: the physics of what could have happened but did not. Inspired by chaos theory and the fractal structure widespread in atmospheric physics, Palmer has developed a new underlying structure for quantum theory, with radical implications for our fundamental principles of quantum physics; the limits of quantum computation; and perhaps even the search for quantum gravity.

Testing quantum observers on quantum computers with Dr Will Zeng
What if you could put an observer in superposition on a quantum computer? Dr Will Zeng suggests that this experiment could stretch standard quantum theory so far that it might break — and radically update our understanding of physical reality. However, today's proof-of-principle experiments on quantum computers use single qubits to model observers. Zeng explains how a new programme of research aims to quantify "observer-ness" and conduct experiments with increasingly realistic observers, pushing quantum computers to the limits until they can run actual quantum Artificial General Intelligence experiments.

Conservation laws with Dr Chiara Marletto
Our most far-reaching principles of physics are not about what changes, but what stays the same: conservation laws. In this episode of the Quantum Foundations Podcast, Dr Chiara Marletto from the University of Oxford explains how such principles enable discovery of new physical phenomena; their central role in thermodynamics; controversies about how they hold up in quantum mechanics; and how they can be used to formulate results about future theories of physics beyond quantum.

Quantum, cryptography & metacomplexity with Oxford Computer Scientist Matthew Gray
You’ve heard of cryptography. Perhaps quantum cryptography too. Maybe even post-quantum cryptography. But what about *quantum post-quantum cryptography*?! When this came up in conversation with Oxford Computer Scientist Matthew Gray recently, I’d never heard of it. I wanted to know more, so I invited him for a podcast. Turns out, there’s a whole world of layers to unravel linking quantum and cryptography — or even multiple worlds… In this discussion, we dip into those, and how this all relates to “metacomplexity” problems: the hardness of figuring out the hardness of a problem. Listen to this episode if you want to ex...

A quantum theory of time with Dr Simone Rijavec
What if time isn’t fundamental — but emerges from quantum mechanics itself? In this episode, Dr Simone Rijavec explains how a timeless quantum universe can still give rise to the illusion of time flowing. We unpack the Wheeler–DeWitt equation, the Page–Wootters model of relational time, and how these ideas connect to the multiverse and quantum gravity. Dr Rijavec is a postdoctoral researcher at Tel Aviv University and former PhD researcher at the University of Oxford.

Ivette Fuentes: The Breakthrough We Can Test Right Now
Professor Ivette Fuentes makes impossible physics testable, with verified predictions on the Casimir effect and quantum vacuum. Now she's building a "third way" to quantum gravity, a surprisingly simple model that changes both quantum mechanics and relativity instead of forcing one to dominate the other.

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 t...

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.

Locality in Quantum Physics Explained with Dr Nicetu Tibau Vidal
Welcome to Episode 1 of my new Quantum Foundations podcast! I interview Dr Nicetu Tibau Vidal, a Research Fellow at the University of Hong Kong. We discuss locality in quantum physics, informed by Nicetu's PhD research at the University of Oxford and his ongoing work. It is often stated that "if two particles are quantum entangled, doing something to one instantly influences a distant entangled particle." This statement is backed by Bell's Theorem, said to require sacrificing locality (distant particles can't instantly influence each other) or realism (our theories describe real aspects of the universe).
