Query: Experimental demonstration of high-dimensional photonic spatial
  entanglement between multi-core optical fibers   Fiber transport of multi-dimensional photonic qudits promises high
information capacity per photon without space restriction. This work
experimentally demonstrates transmission of spatial qudits through multi-core
optical fibers and measurement of the entanglement between two fibers with
quantum state analyzers, each composed of a spatial light modulator and a
single-mode fiber. Quantum state tomography reconstructs the four-dimension
entangled state that verifies the non-locality through concurrences in
two-dimensional subspaces and a high-dimensional Bell-type CGLMP inequality.
