    Multipartite entanglement distribution in a topological photonic network by Juan Zurita, Andrés Agustí Casado, Charles E. Creffield, Gloria Platero

    Published 2025-02-01
    “…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. …”
