Abstract
Entanglement swapping is a core ingredient of a quantum repeater and requires that quantum correlations be established between independent photons. Entanglement swapping also implies that a quantum state has been teleported between two parties. Here we outline recent work in entanglement swapping with spatial modes of light. We show quantum correlations between photons that have never interacted, and demonstrate this in both a two-dimensional and high-dimensional subspace using orbital angular momentum. Finally, we outline a ghost imaging experiment across a virtual link, where object and image are linked through photons with no initial position correlations.
