Journal ArticleDOI
Number-phase entanglement and Einstein-Podolsky-Rosen steering
TL;DR: In this paper, the uncertainty relation between the operators associated with the total number of particles and with the relative phase of two bosonic modes is used to construct entanglement and Einstein-Podolsky-Rosen steering criteria.
Journal ArticleDOI
Distribution and quantification of remotely generated Wigner negativity
TL;DR: In this paper , the authors investigated the shareability of generated Wigner negativity in the multipartite scenario from a quantitative perspective, and established a monogamy relation akin to the generalized Coffman-Kundu-Wootters inequality.

TL;DR: In this article , a graph-theoretical programmable quantum photonic device is demonstrated in very large-scale integrated nanophotonic circuits, using graph theory to describe and design quantum components, devices, setups and systems.
Journal ArticleDOI
Efficient Scheme for Perfect Collective Einstein-Podolsky-Rosen Steering
TL;DR: It is demonstrated that by tuning the laser frequency to the blue (anti-Stokes) sideband of the average frequency of the cavity modes, the modes become mutually coherent and then may collectively steer the mirror mode to a perfect Einstein-Podolsky-Rosen state.
Journal ArticleDOI
Quasi-Fine-Grained Uncertainty Relations
TL;DR: In this paper, a general quasi-fine-grained uncertainty relation (QFGUR) was proposed to quantitatively link the uncertainty to entanglement and EPR steering.
