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…
