  We experimentally realize "hybrid" entanglement swapping between
discrete-variable (DV) and continuous-variable (CV) optical systems. DV
two-mode entanglement as obtainable from a single photon split at a beam
splitter is robustly transferred by means of efficient CV entanglement and
operations, using sources of squeezed light and homodyne detections. The DV
entanglement after the swapping is verified without post-selection by the
logarithmic negativity of up to 0.28$\pm$0.01. Furthermore, our analysis shows
that the optimally transferred state can be post-selected into a highly
entangled state that violates a Clauser-Horne-Shimony-Holt inequality by more
than four standard deviations, and thus it may serve as resources for quantum
teleportation and quantum cryptography.
