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 …

We develop a resource theory for continuous-variable systems grounded on operations
routinely available within current quantum technologies. In particular, the set of free …

Quantum non-Gaussian states of photons and phonons are conclusive and direct witnesses
of higher-than-quadratic nonlinearities in optical and mechanical processes. Moreover, they …

Entanglement distillation is an indispensable ingredient in extended quantum
communication networks. Distillation protocols are necessarily non-deterministic and require …

We introduce a family of criteria to detect quantum non-Gaussian states of a harmonic
oscillator, that is, quantum states that cannot be expressed as a convex mixture of Gaussian …

We address detection of quantum non-Gaussian states, ie, nonclassical states that cannot
be expressed as a convex mixture of Gaussian states, and present a method to derive a new …

We report on the experimental verification of quantum non-Gaussian character of a heralded
single-photon state with a positive Wigner function. We unambiguously demonstrate that the …

We introduce a new state called photon-added-and-subtracted two modes pair coherent
state (PAASTMPCS) by simultaneously adding and subtracting photons to the different …

Conditional addition of photons represents a crucial tool for optical quantum state
engineering and it forms a fundamental building block of advanced quantum photonic …

Pair coherent states (PCSs) as a kind of two-mode non-Gaussian and nonclassical states
were introduced and studied. Some nonclassical characteristics of them such as two-mode …
