We extend the framework of general boundary quantum field theory (GBQFT) to achieve a fully local description of realistic quantum field theories. This requires the quantization of non-Kähler polarizations, which occur generically on timelike hypersurfaces in Lorentzian spacetimes, as has been shown...
