Note on episodes in the history of modeling measurements in local spacetime regions using QFT

Doreen Fraser, Maria Papageorgiou

The formulation of a measurement theory for relativistic quantum field theory (QFT) has recently been an active area of research. In contrast to the asymptotic measurement framewor…

Particle-field duality in QFT measurements

Maria Papageorgiou, Jose de Ramon, Charis Anastopoulos

Pointlike systems coupled to quantum fields are often employed as toy models for measurements in quantum field theory. In this paper, we identify the field observables recorded by…

Eliminating the "impossible": Recent progress on local measurement theory for quantum field theory

Maria Papageorgiou, Doreen Fraser

Arguments by Sorkin arXiv:gr-qc/9302018 and Borsten, Jubb, and Kells arXiv:1912.06141 establish that a natural extension of quantum measurement theory from non-relativistic quantum…

Causality and signalling in non-compact detector-field interactions

José de Ramón, Maria Papageorgiou, Eduardo Martín-Martínez

In this paper we analyze the problem of "apparent" superluminal signalling and retrocausation that can appear for particle detector models when considering non-compactly supported…

Relativistic causality in particle detector models: Faster-than-light signalling and "Impossible measurements"

José de Ramón, Maria Papageorgiou, Eduardo Martín-Martínez

We analyze potential violations of causality in Unruh DeWitt-type detector models in relativistic quantum information. We proceed by first studying the relation between faster-than…

Impact of relativity on particle localizability and ground state entanglement

Maria Papageorgiou, Jason Pye

Can a relativistic quantum field theory be consistently described as a theory of localizable particles? There are many known issues with such a description, indicating an answer in…
