TL;DR
This paper introduces a geometrical entanglement criterion that provides simple, experimentally accessible conditions for detecting entanglement, along with a generalized approach that offers a complete separability test and a broader set of entanglement identifiers.
Contribution
It proposes a new geometrical criterion for entanglement detection that is both simple and experimentally friendly, and extends it to a necessary and sufficient condition with a richer set of identifiers.
Findings
The criterion is illustrated with several examples.
A generalized approach provides a complete separability condition.
The method introduces a family of entanglement identifiers richer than witnesses.
Abstract
We present an intuitive geometrical entanglement criterion. It allows formulation of simple and experimentally friendly sufficient conditions for entanglement. The conditions are illustrated with several examples. Moreover, a generalization of our approach is a necessary and sufficient separability condition. It can be associated with a family of entanglement identifiers, which is strictly richer than the family of entanglement witnesses.
