Hybrid entanglement in heterogeneous quantum networks

The building of quantum networks is stimulating the development of multiple physical platforms and different types of encodings in a heterogeneous structure allowing full functionality. Central to this endeavour is the capability to distribute and interconnect optical entangled states relying on different discrete and continuous quantum variables. Here, we report an entanglement swapping protocol involving single-photon entanglement and hybrid entanglement between particle- and wave-like optical qubits and demonstrate the creation of hybrid entanglement heralded by a specific Bell-state measurement. This ability opens up the prospect of connecting heterogeneous nodes of a network, with the promise of increased integration and functionalities.
