Quantifications for multimode entanglement
Mehmet Emre Taşgın, Muhammad Suhail Zubairy · Physical Review A · 2020
We introduce two independent quantifications for three-mode and four-mode entanglement. We investigate the conversion of one type of nonclassicality, i.e., single-mode nonclassicality, into another type of nonclassicality, i.e., multimode entanglement, in beam splitters. We observe parallel behavior of the two quantifications. The methods can be generalized to the quantification of any multimode entanglement.
