From: Multipartite state generation in quantum networks with optimal scaling
2D-cluster building blocks in a windmill formation with a block size of (a) two or (b) four. (c) The blocks can be connected to a larger cluster state. The connection operations are performed on the qubits in the rectangles, which are stored at the same repeater station. Note that only two qubits per copy need to be stored at each location.
