Quantifying tripartite entanglement with entropic correlations
James Schneeloch, Christopher C. Tison, Michael L. Fanto, Shannon Ray, Paul M. Alsing · Physical Review Research · 2020
The authors develop techniques to quantify multipartite and high-dimensional entanglement using information-based measures of correlation and uncertainty, and show the large amounts of multi-partite entanglement available in photon triplets generated in third-order Spontaneous Parametric Down-Conversion
