Abstract 
We study a model for the initial state of the universe based on a gravitational path integral that includes connected geometries which simultaneously produce bra and ket of the wave function. A natural object to describe this state is the Wigner distribution, which is a function on a classical phase space obtained by a certain integral transform of the density matrix. I will discuss a toy two-dimensional model (de Sitter JT gravity) where we find semiclassical saddle-points of this type, where the connected geometry dominates over the Hartle-Hawking saddle and gives a distribution that has a meaningful probabilistic interpretation for local observables. Moreover, I will report some preliminary results on these type of solutions in four space-time dimensions.
