چکیده
We study the genuine multipartite entanglement in tripartite quantum systems by using principal basis matrix representations of density matrices. Using Schmidt decomposition and local unitary transformation, we first convert general states to simpler forms then construct some special matrices from correlation tensors simplified Based on different linear combinations these matrices, necessary conditions are presented detect states. Detailed examples show that our method can more entangled than previous ones.

Genuine Multipartite Entanglement without Multipartite Correlations.
Nonclassical correlations between measurement results make entanglement the essence of quantum physics and the main resource for quantum information applications. Surprisingly, there are n-particle states which do not exhibit n-partite correlations at all but still are genuinely n-partite entangled. We introduce a general construction principle for such states, implement them in a multiphoton e...
متن کاملDetection of high-dimensional genuine multipartite entanglement of mixed states.
We derive a general framework to identify genuinely multipartite entangled mixed quantum states in arbitrary-dimensional systems and show in exemplary cases that the constructed criteria are stronger than those previously known. Our criteria are simple functions of the given quantum state and detect genuine multipartite entanglement that had not been identified so far. They are experimentally a...
متن کاملNonlocal Nondegenerate Optical Parametric Amplifier Based on Genuine Multipartite Entanglement
We propose a new scheme for realizing nonlocal nondegenerate optical parametric amplifier by means of genuine four-mode entanglement. The nondegenerate optical parametric amplifier is regarded as a unitary transformation from two input fields to two outputs. Two inputs and two outputs are located at the remote stations respectively. Employing off-line four-mode entanglement, homodyne detection,...
متن کاملDevice-independent witnesses of genuine multipartite entanglement.
We consider the problem of determining whether genuine multipartite entanglement was produced in an experiment, without relying on a characterization of the systems observed or of the measurements performed. We present an n-partite inequality that is satisfied by all correlations produced by measurements on biseparable quantum states, but which can be violated by n-partite entangled states, suc...
