Abstract: This work marks an important progress towards practical quantum optical technologies in the continuous variable regime, as it shows the feasibility of experiments where non-Gaussian state generation entirely relies on plug-&-play components from guided-wave optics technologies. This strategy is demonstrated experimentally with the heralded preparation of low amplitude Schr\"odinger cat states based on single-photon subtraction from a squeezed vacuum. All stages of the experiment are based on off-the-shelf fiber components. This leads to a stable, compact, and easily re-configurable realization, fully compatible with existing fibre networks and, more in general, with future out-of-the-laboratory applications.

Climbing the Fock ladder: Advancing multiphoton state generation [0.0]
A scheme for the enhanced generation of higher photon-number states is realized, using an optical time-multiplexing setting. We use a quantum feedback mechanism for already generated photons to induce self-seeding of the consecutive nonlinear process. We compare the fidelities and success probabilities of our protocol with the common direct heralding of photon-number states.

Non-Gaussian states of an optical field are important as a proposed resource in quantum information applications. We propose a novel approach involving displacement of the ancilla field into the regime where mesoscopic detectors can be used. We conclude that states with strong Wigner negativity can be prepared at high rates by this technique under experimentally attainable conditions.
