Integration against POVMs in von Neumann algebras and Operational Quantum Reference Frames
Jan Głowacki, Yui Kuramochi
We construct integrals of uniformly bounded ultraweakly measurable functions against positive operator-valued measures (POVMs) in von Neumann algebras, assuming that the integrand…
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…
Operational Quantum Frames: An operational approach to quantum reference frames
Jan Głowacki
The quantum reference frames program is based on the idea that reference frames should be treated as quantum physical systems. In this work, we combine these insights with the emph…
Operational Quantum Reference Frame Transformations
Titouan Carette, Jan Głowacki, 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…
Quantum Reference Frames on Finite Homogeneous Spaces
Jan Głowacki, Leon Loveridge, James Waldron
We present an operationally motivated treatment of quantum reference frames in the setting that the frame is a covariant positive operator valued measure (POVM) on a finite homogen…
Groupoid symmetry, constraints and quantization of General Relativity
Jan Marcin Głowacki
The purpose of the current paper is twofold: to provide a conceptual link between the quantization framework based on Lie integration of algebroids proposed by N.P. Landsman in the…
