Quantum Reference Frames on Homogeneous Spaces
Jan GÅowacki
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…
Foundations of Relational Quantum Field Theory I: Scalars
Samuel Fedida, Jan GÅowacki
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…
Operational Quantum Reference Frame Transformations
Titouan Carette, Jan GÅowacki, Leon Loveridge
Quantum reference frames are needed in quantum theory for much the same reasons that reference frames are in classical theories: to manifest invariance in line with fundamental rel…
Towards Relational Quantum Field Theory
Jan GÅowacki
This paper presents a research program aimed at establishing relational foundations for relativistic quantum physics. Although the formalism is still under development, we believe…
