Although the theoretical trade-off between the quantity and quality of children is wellestablished, empirical evidence supporting such a causal relationship − particularly on child health − is limited.

The notion that any physical quantity is defined and measured relative to a reference frame is traditionally not explicitly reflected in the theoretical description of physical experiments where, instead, the relevant observables are typically represented as “absolute” quantities. However, the emergence of the resource theory of quantum reference frames as a new branch of quantum information sc...
