Loss of non-Gaussianity for damped photon-subtracted thermal states
Iulia Ghiu, Paulina Marian, Tudor A. Marian
We investigate non-Gaussianity properties for a set of classical one-mode states obtained by subtracting photons from a thermal state. Three distance-type degrees of non-Gaussianit…
Relative entropy is an exact measure of non-Gaussianity
Paulina Marian, Tudor A. Marian
We prove that the closest Gaussian state to an arbitrary -mode field state through the relative entropy is built with the covariance matrix and the average displacement of the g…
Characterization of phase-averaged coherent states
Alessia Allevi, Maria Bondani, Paulina Marian +2
We present the full characterization of phase-randomized or phase-averaged coherent states, a class of states exploited in communication channels and in decoy state-based quantum k…
