We introduce a geometric path integral definition of wormhole partition functions in a general class of 1D quantum systems obtained by quantizing a phase space. We compute the wormhole partition function in a semi-classical limit and in some simple examples. The partition function of the n-fold wormhole is found to be identical to the n-th Renyi entropy of a thermal mixed state of the doubled system. This mixed state incorporates three types of quantum statistical behavior: classically correlated, quantum entangled, and classically uncorrelated. We apply our prescription to 2D CFTs with Virasoro symmetry and recover the holographic dual formulation in terms of AdS3 gravity.

A thermofield-double model of Uhlmann anholonomy
For a thermofield double model, Uhlmann parallel transport acts as optimal filtering measurements on one side and as holonomic quantum gates on the other, with an iSWAP gate constructible from geodesic triangles.

Hilbert Bundles and Holographic Space-time: the Hydrodynamic Approach to Gravity
Einstein's equations are treated as hydrodynamic equations for the area-law entropy of causal diamonds, with quantum dynamics proposed to live in a Hilbert bundle over spacetime geodesics.
