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

“…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. …”

Time Division Switching Scheme and Performance Analysis of Low Orbit Quantum Satellite Communication by Guang Yang, Min Nie, Fan Jiang

“…To overcome the delay in satellite-earth link and satellite-satellite link, a switching and transmission method was proposed based on quantum channel byte, which decreased the average qubit transmission delay for single time slot. Performance analysis shows that the number of time slot and the length of quantum channel byte have the key influence on the user number, the traffic and the call of loss. …”
