In the field of continuous-variable quantum information processing, non-Gaussian states
with negative values of the Wigner function are crucial for the development of a fault-tolerant …

Non-Gaussian states are essential for many optical quantum technologies. The so-called
optical quantum state synthesizer (OQSS), consisting of Gaussian input states, linear optics …

In optical quantum information processing with continuous variables, optical non-Gaussian

Hybrid entanglement between discrete-variable (DV) and continuous-variable (CV) quantum
systems is an essential resource for heterogeneous quantum networks. Our previous work …

The cat code is a promising encoding scheme for bosonic quantum error correction as it
allows for correction against losses—the dominant error mechanism in most bosonic …

In our paper, we compare three teleportation protocols: The original protocol, the photon
subtraction protocol, and the protocol with a cubic phase gate. We evaluate the fidelity of …

The paper considers the possibility of generating different non-Gaussian states using the
entangled state photon measurement scheme. In the paper, we have proposed a way to …

In this survey, we present single-photon states of electromagnetic fields, discuss discrete
measurements of a single-photon field, show how a linear quantum system responds to a …

Decoherence is detrimental to quantum key distribution (QKD) over large distances. One of
the proposed solutions is to use quantum repeaters, which divide the total distance between …

Quantum state tomography is an essential component of modern quantum technology. In
application to continuous-variable harmonic-oscillator systems, such as the electromagnetic …
