Foundations of Relational Quantum Field Theory I: Scalars
Samuel Fedida, Jan Głowacki
We develop foundations for a relational approach to quantum field theory (RQFT) based on the operational quantum reference frames (QRFs) framework considered in a relativistic sett…
Quantum Reference Frames on Homogeneous Spaces
Jan Głowacki
This paper initiates a systematic study of operators arising as integrals of operator-valued functions with respect to positive operator-valued measures and utilizes these tools to…
Towards Relational Quantum Field Theory
Jan Głowacki
This paper presents a research program aimed at establishing relational foundations for relativistic quantum physics. Although the formalism is still under development, we believe…
Relativization is naturally functorial
Jan Głowacki
In this note, we provide some categorical perspectives on the relativization construction arising from quantum measurement theory in the presence of symmetries and occupying a cent…
