Show affiliationsIn the context of canonical quantum gravity we study an alternative real quantization scheme, which arises by relating simpler Riemannian quantum theory to the more complicated physical Lorentzian theory, the generalized Wick transform. On the symmetry reduced models, homogeneous Bianchi cosmology and 2 + 1 gravity, we investigate its generalized construction principle, demonstrate that the emerging quantum theory is equivalent to that obtained from standard quantization and how to obtain physical states in Lorentzian gravity from Wick transforming solutions of Riemannian quantum theory.
