The meaning and implications of the Extended Wigner's friend thought experiment are still highly debated. A number of assumptions taken in the argument are very foundational in content, and therefore cannot be given up easily. However, the questions remains whether there are "hidden" assumptions that do not explicitly appear in the argument. The authors themselves seem to favour the rejection of their (implicit) assumption that macroscopic agents can be modelled as physical systems by quantum theory. Their rejection then renders their conclusion that "quantum theory cannot be extrapolated to complex systems, at least not in a straightforward manner". On the other hand, one presentation of the experiment as a quantum circuit models the agents as single qubits and their reasoning as simple conditional operations.
