The View from Within: What Can Embedded Observers (Not) Learn?

Tomáš Gonda, Johannes Fankhauser, Gemma De les Coves

Physics is usually done from a third-person perspective, as if the world were described from outside. Yet, observers are themselves physical systems within the world they observe.…

Interpreting Quantum Learning Models via Stochastic Processes

Johannes Fankhauser, Lukas J. Fiderer, Hans J. Briegel

Quantum machine learning models define probabilistic input--output maps through coherent quantum evolution and measurement. While such models can exhibit computational advantages,…

Observability and Predictability in Quantum and Post-Quantum Physics

Johannes Fankhauser

I introduce a framework to distinguish two domains of physics - the manifest (i.e. the directly observable empirical records in terms of manifest configurations) and the non-manife…

Epistemic Horizons From Deterministic Laws: Lessons From a Nomic Toy Theory

Johannes Fankhauser, Tomáš Gonda, Gemma De les Coves

Quantum theory has an epistemic horizon, i.e. exact values cannot be assigned simultaneously to incompatible physical quantities. As shown by Spekkens' toy theory, positing an epis…

Epistemic Boundaries and Quantum Uncertainty: What Local Observers Can (Not) Predict

Johannes Fankhauser

One of quantum theory's salient features is its apparent indeterminism, i.e. measurement outcomes are typically probabilistic. We formally define and address whether this uncertain…
