Entanglement is one of the most distinguishing features of multi-partite quantum systems and, appropriately, a crucial resource in quantum information science. An important technique to aid in harnessing this resource is entanglement swapping, which enables entanglement of distant quantum systems and thereby the long-range distribution of quantum correlations, in addition to shedding light on the fundamental nature and extent of quantum non-locality. Our work investigates how to achieve entanglement swapping and characterize the entanglement of photon pairs entangled in the continuous spectral-temporal degree of freedom. This allows unprecedented control over a large Hilbert space and can be applied to the spatial-momentum degrees of freedom as well.
