Direct generation and characterization of continuous-variable multipartite entanglement

We demonstrated the direct generation of multipartite continuous-variable entanglement and investigated its robustness against losses. This led to the development of experimental capabilities to fully characterize a six-mode quantum optical state.

Determination of Continuous Variable Entanglement by Purity Measurements

Gerardo Adesso, Alessio Serafini, Fabrizio Illuminati

We classify the entanglement of two-mode Gaussian states according to their degree of total and partial mixedness. We derive exact bounds that determine maximally and minimally entangled states for fixed global and marginal purities. This characterization allows for an experimentally reliable estimate of continuous variable entanglement based on measurements of purity.
