TU Wien and IST have analyzed the distribution of entanglement over long distances by driving separated quantum nodes with the output of a two-mode squeezed parametric amplifier. This scheme is very robust with respect to various imperfections and is ideally suited for microwave-to-optics entanglement generation using the electro-optical device implemented at IST. Read more details about this scheme in the preprint: arXiv:2204.02993.
