Query: From sources to initial data and back again: on bulk singularities in
  Euclidean AdS/CFT   A common method to prepare states in AdS/CFT is to perform the Euclidean path
integral with sources turned on for single-trace operators. These states can be
interpreted as coherent states of the bulk quantum theory associated to
Lorentzian initial data on a Cauchy slice. In this paper, we discuss the extent
to which arbitrary initial data can be obtained in this way. We show that the
initial data must be analytic and define the subset of it that can be prepared
by imposing bulk regularity. Turning this around, we show that for generic
analytic initial data the corresponding Euclidean section contains
singularities coming from delta function sources in the bulk. We propose an
interpretation of these singularities as non-perturbative objects in the
microscopic theory.
