DOI: 10.1088/1367-2630/ac0204
Abstract: Non-Gaussian states of an optical field are important as a proposed resource in quantum information applications. While conditional preparation is a highly successful approach to preparing such states, their quality is limited by detector non-idealities… read more here.

DOI: 10.1088/1674-1056/ac401f
Abstract: Realistic quantum systems always exhibit gravitational and relativistic features. In this paper, we investigate the properties of Gaussian steering and its asymmetry by the localized two-mode Gaussian quantum states, instead of the traditional single-mode approximation… read more here.

DOI: 10.1103/physreva.100.062308
Abstract: In the space of quantum channels, we establish the geometry that allows us to make statistical predictions about relative volumes of entanglement breaking channels among all the Gaussian quantum channels. The underlying metric is constructed… read more here.
