  A three-qubit quantum network node based on trapped atomic ions is presented.
The ability to establish entanglement between each of the qubits in the node
and a separate photon that has travelled over a 101km-long optical fiber is
demonstrated. By sending those photons through the fiber in close succession, a
remote entanglement rate is achieved that is greater than when using only a
single qubit in the node. Once extended to more qubits, this multimode approach
can be a useful technique to boost entanglement distribution rates in future
long-distance quantum networks of light and matter.
