  In the ongoing effort towards a scalable quantum computer, multiple
technologies have been proposed. Some of them exploit topological materials to
process quantum information. In this work, we propose a lattice of photonic
cavities with alternating hoppings to create a modified multidomain SSH chain,
that is, a sequence of topological insulators made from chains of dimers. A
qubit is then coupled to each boundary. We show this system is well suited for
quantum information processing because topological transfer of photons through
this one-dimensional lattice can entangle any set of qubits on demand,
providing a scalable quantum platform. We verify this claim evaluating
entanglement measures and witnesses proving that bipartite and multipartite
entanglement is produced, even in the presence of some disorder.
