No-Go Theorem for Gaussian Quantum Error Correction
We prove that Gaussian operations are of no use for protecting Gaussian states against Gaussian errors in quantum communication protocols. Specifically, we introduce a new quantity characterizing any single-mode Gaussia...

When Non-Gaussian States are Gaussian: Generalization of Non-Separability Criterion for Continous Variables
We present a class of non-Gaussian two-mode continuous-variable states for which the separability criterion for Gaussian states can be employed to detect whether they are separable or not. These states reduce to the two-mode Gau...

Gaussian Transformations and Distillation of Entangled Gaussian States
We prove that it is impossible to distill more entanglement from a single copy of a two-mode bipartite entangled Gaussian state via local Gaussian operations and classical communication. More generally, we show that any hypothetical...

Gaussian quantum adaptation of non-Gaussian states for a lossy channel
The Gaussian quantum adaptation deterministically protecting a negativity of a Wigner function of a non-Gaussian quantum state transmitted through a lossy channel is proposed. For the pure non-Gaussian states, an optimized ...

Quantization of Hermite-Gaussian and Laguerre-Gaussian beams and their spatial transformations
The paraxial quantum propagation of wavepackets is studied. Hermite-Gaussian and Laguerre-Gaussian beams are considered with respective expansions. A description of free-space propagation and transformation of radiation by optical s...

Directional Splitting for Structure Adaptation of Bayesian Filters
. The state is estimated within the Bayesian framework using the Gaussian filter and the Gaussian mixture filter. The paper is concerned with the joint Gaussianity assumption of the Gaussian filter and monitoring i...

Experimental Quantum Non-Gaussian Coincidences of Entangled Photons
Quantum non-Gaussianity, a more potent and highly useful form of nonclassicality, excludes all convex mixtures of Gaussian states and Gaussian parametric-Gaussian coincidences of entangled photon pairs with the Cla...
