Experimentally friendly geometrical criteria for entanglement.
نویسندگان
چکیده
A simple geometrical criterion gives experimentally friendly sufficient conditions for entanglement. Its generalization gives a necessary and sufficient condition. It is linked with a family of entanglement identifiers, which is strictly richer than the family of entanglement witnesses.

Efficient entanglement criteria beyond Gaussian limits using Gaussian measurements.
We present a formalism to derive entanglement criteria beyond the Gaussian regime that can be readily tested by only homodyne detection. The measured observable is the Einstein-Podolsky-Rosen (EPR) correlation. Its arbitrary functional form enables us to detect non-Gaussian entanglement even when an entanglement test based on second-order moments fails. We illustrate the power of our experiment...
متن کاملExamining the dimensionality of genuine multipartite entanglement
Entanglement in high-dimensional many-body systems plays an increasingly vital role in the foundations and applications of quantum physics. In the present paper, we introduce a theoretical concept which allows to categorize multipartite states by the number of degrees of freedom being entangled. In this regard, we derive computable and experimentally friendly criteria for arbitrary multipartite...
متن کاملSeparability conditions from entropic uncertainty relations
Separability is the property that distinguishes statistical ensembles that have a classical description from the ones that need a quantum description. As a matter of fact, the definition of entanglement is the formal negation of the separability condition [1]. In spite of this clear logical distinction between separable and entangled states, the borderline between these two sets is very difficu...
متن کاملDetection of quantum entanglement in physical systems
Quantum entanglement is a fundamental concept both in quantum mechanics and in quantum information science. It encapsulates the shift in paradigm, for the description of the physical reality, brought by quantum physics. It has therefore been a key element in the debates surrounding the foundations of quantum theory. Entanglement is also a physical resource of great practical importance, instrum...
متن کاملExperimental investigation of criteria for continuous variable entanglement.
We generate a pair of entangled beams from the interference of two amplitude squeezed beams. The entanglement is quantified in terms of EPR paradox and inseparability criteria, with both results clearly beating the standard quantum limit. We experimentally analyze the effect of decoherence on each criterion and demonstrate qualitative differences. We also characterize the number of required and...
