The distribution of entanglement between separated nodes of a quantum network is a fundamental task for almost all quantum communication and quantum information processing applications. While optical photons are the only way to distribute quantum states over very large distances, for on-chip communication also microwave photons or even propagating phonons, i.e., quantized sound waves, can be used for this task. Our goal is to find more and more efficient ways to interface these information carriers with stationary superconducting qubits or spin-based quantum memories and to develop new protocols for a fast and robust distribution of entanglement across large-scale quantum networks.
