A relational quantum field theory for scalars is built from Poincaré-covariant quantum reference frames, yielding local observables and fields that satisfy causality and reproduce key Wightman and Algebraic QFT properties.
Lattice QED is established as a quantum error-correcting code beyond stabilizers, with explicit recovery operations constructed via quantum reference frames for gauge and fermionic sectors.
Causal reference frame and time-delocalized subsystem descriptions of pure processes are coordinate parametrizations of a single neutral object, with unitary perspective transformations possible by reshuffling time order or adding reference-frame subsystems.
The metric is reinterpreted as relational information carried by local correlations with a quantum reference frame, yielding the nonlinear Einstein equation via a conditional entropy constraint with scalar curvature equal to the cosmological constant.
