Quantum speed of evolution in a Markovian bosonic environment
Paulina Marian, Tudor A. Marian
We present explicit evaluations of quantum speed limit times pertinent to the Markovian dynamics of an open continuous-variable system. Specifically, we consider the standard setti…
Einstein-Podolsky-Rosen uncertainty limits for bipartite multimode states
Paulina Marian, Tudor A. Marian
Certification and quantification of correlations for multipartite states of quantum systems appear to be a central task in quantum information theory. We give here a unitary quantu…
A geometric measure of non-classicality
Paulina Marian, Tudor A. Marian
This paper aims to stress the role of the Cahill-Glauber quasi-probability densities in defining, detecting, and quantifying the non-classicality of field states in quantum optics.…
Modification of polarization through de-Gaussification
Iulia Ghiu, Paulina Marian, Tudor A. Marian
We analyze the polarization of a quantum radiation field under a de-Gaussification process. Specifically, we consider the addition of photons to a two-mode thermal state to get mix…
Einstein-Podolsky-Rosen-like separability indicators for two-mode Gaussian states
Paulina Marian, Tudor A. Marian
We investigate the separability of the two-mode Gaussian states by using the variances of a pair of Einstein-Podolsky-Rosen (EPR)-like observables. Our starting point is inspired b…
Quantum Fisher information on two manifolds of two-mode Gaussian states
Paulina Marian, Tudor A. Marian
We investigate two special classes of two-mode Gaussian states of light that are important from both the experimental and theoretical points of view: the mode-mixed thermal states…
