  Superconducting and photonic technologies are envisioned to play a key role
in the Quantum Internet. However the hybridization of these technologies
requires functional quantum transducers for converting superconducting qubits
into "flying" qubits able to propagate through the network (and vice-versa). In
this paper, quantum transduction is theoretically investigated for a key
functionality of the Quantum Internet, namely, multipartite entanglement
distribution. Different communication models for quantum transduction are
provided, in order to make the entanglement distribution possible. The proposed
models departs from the large heterogeneity of hardware solutions available in
literature, abstracting from the particulars of the specific solutions with a
communication engineering perspective. Then, a performance analysis of the
proposed models is conducted through key communication metrics, such as quantum
capacity and entanglement generation probability. The analysis reveals that --
although the considered communication metrics depend on transduction hardware
parameters for all the proposed models -- the particulars of the considered
transduction paradigm play a relevant role in the overall entanglement
distribution performance.
