"generating large-scale entanglement directly is difficult due to probabilistic photon loss/ complex optical requirements... overcome sequentially merging smaller cluster states with high fidelity, creating efficient assembly line for complex quantum entanglement... significantly reduces hardware overhead... provides bridge between localized superconducting processors/ distributed photonic quantum networks... scalable, fault-tolerant, measurement-based quantum computing/ telecommunications"
