We introduce a measure to quantify the non-Gaussian character of a quantum state: the
quantum relative entropy between the state under examination and a reference Gaussian …

We address the estimation of the loss parameter of a bosonic channel probed by arbitrary

We propose a measure of non-Gaussianity for quantum states of a system of n oscillator
modes. Our measure is based on the quasi-probability Q (α), α ∈ C^ n. Since any measure …

We study the continuous-variable quantum teleportation of states, statistical moments of
observables, and scale parameters such as squeezing. We investigate the problem both in …

Continuous Variable (CV) non-Gaussian resources are fundamental in the realization of

superposition of number-conserving operations - IOPscience Skip to content IOP Science …

Performance of quantum teleportation is typically measured by the average fidelity, an
overlap between the input and output states. Along with the first moment, we introduce the …

We analyze effects of squeezing upon superpositions of coherent states (SCSs) and
entangled coherent states for Bell-inequality tests. We find that external squeezing can …

We investigate the continuous-variable entanglement swapping protocol in a non-Gaussian
setting, with non-Gaussian states employed either as entangled inputs and/or as swapping …
