Qubit teleportation between non-neighbouring nodes in a quantum network

Abstract Future quantum internet applications will derive their power from the ability to share quantum information across the network 1,2 . Quantum teleportation allows for the reliable transfer of quantum information between distant nodes, even in the presence of highly lossy network connections 3 . Although many experimental demonstrations have been performed on different quantum network platforms 4–10 , moving beyond directly connected nodes has, so far, been hindered by the demanding requirements on the pre-shared remote entanglement, joint qubit readout and coherence times. Here we realize quantum teleportation between remote, non-neighbouring nodes in a quantum network. The network uses three optically…
