Utilizing Degeneracy in a Few-Mode Fiber to Demonstrate Entanglement Distribution
The degenerate modes of a few-mode fiber retain entanglement and allow for distribution over 50-km of single-mode fibers, paving the way for future research towards multi-port bidirectional beam splitters with a consistent coupling ratio across the C-band and over time, potentially maintaining hyperentanglement.
