  Long range quantum information processing will require the integration of
different technologies to form hybrid architectures combining the strengths of
multiple quantum systems. In this work, we propose a hybrid networking
architecture designed to improve entanglement rates in quantum networks based
on trapped ions. Trapped ions are excellent candidates as network nodes but
photon losses make long-distance networking difficult. To overcome some losses
and extend the range of trapped-ion-based networks, we propose including
neutral-atom-based non-destructive single-photon detection and single photon
storage in between networking nodes, forming a hybrid network. This work builds
on recently demonstrated optical frequency conversion of single photons emitted
by trapped ions. We derive the average two-node entanglement rate for this
proposed network architecture as a function of distance. Using reasonable
experimental parameters, we show this proposed quantum network can generate
remote entanglement rates up to a factor of 100 larger than that of an
equivalent homogeneous network at both near-IR and C-band wavelengths for
distances up to 50 km.
