- Abstract: The robust generation and manipulation of entangled multiphoton states
on-chip has an essential role in quantum computation and communication. Lattice
topology has emerged as a means of protecting photonic states from disorder but
entanglement across different topologies remained unexplored. We report
biphoton entanglement between topologically distinct spatial modes in a
bipartite array of silicon waveguides. The results highlight topology as an
additional degree of freedom for entanglement and open avenues for
investigating information teleportation between trivial and topological modes.
