Abstract

A field-theoretic version of Wigner's friend (1961) illustrates how the quantum measurement problem arises for field theory. Similarly, considering space like separate measurements of entangled fields by observers akin to Wigner's friend shows the sense in which relativistic constraints make the measurement problem particularly difficult to resolve in the context of a relativistic field theory. We will consider proposals by Wigner (1961), Bloch (1967), Helwig and Kraus (1970), and Bell (1984) for resolving the measurement problem for quantum field theory. We will conclude by considering the possibility of giving up rich dynamical explanation in the context of a many-maps formulation of relativistic quantum field theory.
