Quantum theory and relativity are the pillar theories on which our understanding of physics is based. Poincaré invariance is a fundamental physical principle stating that the experimental results must be the same in all inertial reference frames in Minkowski spacetime. It is a basic condition imposed on quantum theory in order to construct quantum field theories, hence, it plays a fundamental role in the standard model of particle physics too. As is well known, Minkowski spacetime follows from…

An operational approach to spacetime symmetries: Lorentz transformations from quantum communication

- Physics, Mathematics

In most approaches to fundamental physics, spacetime symmetries are postulated a priori and then explicitly implemented in the theory. This includes Lorentz covariance in quantum field theory and…

In this paper and a companion paper, we show how the framework of information geometry, a geometry of discrete probability distributions, can form the basis of a derivation of the quantum formalism.…

A derivation of quantum theory from physical requirements

Quantum theory (QT) is usually formulated in terms of abstract mathematical postulates involving Hilbert spaces, state vectors and unitary operators. In this paper, we show that the full formalism of…

Towards quantum gravity: a framework for probabilistic theories with non-fixed causal structure

General relativity is a deterministic theory with non-fixed causal structure. Quantum theory is a probabilistic theory with fixed causal structure. In this paper, we build a framework for…

Thermodynamics and the structure of quantum theory

- Physics, Mathematics

This work studies how compatibility with thermodynamics constrains the structure of quantum theory by studying how self-duality and analogues of projective measurements, subspaces and eigenvalues imply important aspects ofquantum theory.

Three-dimensionality of space and the quantum bit: an information-theoretic approach

- Physics, Mathematics
- 2013

It is sometimes pointed out as a curiosity that the state space of quantum two-level systems, i.e. the qubit, and actual physical space are both three-dimensional and Euclidean. In this paper, we…

An effect-theoretic reconstruction of quantum theory

- Physics, Mathematics
- 2019

An often used model for quantum theory is to associate to every physical system a C*-algebra. From a physical point of view it is unclear why operator algebras would form a good description of…

Information Theoretic Axioms for Quantum Theory

In this paper we derive the complex Hilbert space formalism of quantum theory from four simple information theoretic axioms. It is shown that quantum theory is the only non classical probabilistic…

The classical limit of a physical theory and the dimensionality of space

- Physics, Computer Science
- 2013

It is shown that as long as the interaction is pairwise, this is impossible, and quantum mechanics and the three-dimensional space remain the only solution, however, having multi-particle interactions and a generalized notion of “classical field” may open up such a possibility.
