- Abstract: We develop a general formalism, based on the Wigner function representation
of continuous-variable quantum states, to describe the action of an arbitrary
conditional operation on a multimode Gaussian state. We apply this formalism to
several examples, thus showing its potential as an elegant analytical tool for
simulating quantum optics experiments. Furthermore, we also use it to prove
that EPR steering is a necessary requirement to remotely prepare a
Wigner-negative state.

A full characterization of multimode quantum states requires a number of experiments that grows exponentially with the number of modes.
Here we propose an alternative approach where the goal is not to reconstruct the full quantum state, but rather to estimate its characteristic function at a given set of points.

We present a scheme that can prepare non-Gaussian quantum states on-demand, by applying a unitary transformation.
The resulting state exhibits a quantum vortex structure in quadrature space, confirming its non-Gaussian nature.
Such non-Gaussian quantum state also reveals increased entanglement content, as quantified by the Logarithmic Negativity and the Wigner function negative volume.
