Wormholes as red herrings: reflection positivity and the reconstruction of unitary quantum field theories.
Motivated by questions arising from wormholes in quantum gravity, we present a proof that unitary quantum field theories are uniquely determined by their closed-manifold partition function alone. Conversely, we argue that any reflection positive function of closed manifolds arises in this way from a unitary quantum field theory. These results may be viewed as providing a first-principles derivation of holography in quantum gravity, and a characterization of the necessary and sufficient conditions for Hilbert space factorization.
