Abstrakt

We show that the axiom of choice, a basic yet controversial postulate of set theory, together with one of the pillars of our best physical theories, namely the no-signalling principle, may point to a limitation in modelling physical problems using standard mathematics. While it is well known that probabilistic no-signalling resources (such as quantum non-locality) are stronger than deterministic ones, we show - by invoking the axiom of choice - the opposite: functional (deterministic) no-signalling resources can be stronger than probabilistic ones (e.g. stronger than quantum entanglement or non-locality in general). To prove this, we devise a Bell-like game that shows a systematic advantage of functional no-signalling with respect to any probabilistic no-signalling resource.
