Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

Coherent manipulation of quantum states of light is key to photonic quantum information
processing. In this Letter, we show that a passive two-level nonlinearity suffices to implement …

The usage of non-Gaussian states to improve the phase sensitivity of interferometers has
been studied before. In this paper, we introduce the multiphoton catalysis two-mode …

Non-Gaussian operations have been shown to enhance the fidelity of continuous-variable
quantum teleportation. However, a disadvantage of these non-Gaussian operations is that …

Photon addition and subtraction render Gaussian states non-Gaussian. We provide a
quantitative analysis of the change in nonclassicality produced by these processes by …

Bosonic qubits are a promising route to building fault-tolerant quantum computers on a
variety of physical platforms. Studying the performance of bosonic qubits under realistic …

We theoretically analyze phase sensitivity using a parity-detection-based Mach-Zehnder
interferometer (MZI) with the input states generated by performing non-Gaussian operations …

The subtraction or addition of a prescribed number of photons to a field mode does not, in
general, simply shift the probability distribution by the number of subtracted or added …

The preparation of light pulses with well-defined quantum properties requires precise control
at the individual photon level. Here, we demonstrate exact and controlled multi-photon …

We report on the realization of a free-space single-photon absorber, which deterministically
absorbs exactly one photon from an input pulse. Our scheme is based on the saturation of …
