From: Multipartite state generation in quantum networks with optimal scaling
Comparison of numerical results for generating 64 × 64 × 64 cluster states from smaller building blocks with hashing protocols using different architectures. (a) Reachable fidelities with local storage capacities of 1800 qubits for n → 100 protocols. (b) Difference in fidelity Fsg − Fbip between the shifted grid architecture Fsg and the bipartite scheme Fbip for n → 100 protocols. The red area signifies the parameter regime where the multipartite approach (A) achieves higher fidelities. (c) Number of output copies which can be provided with a fidelity of at least 0.9 with local storage capacities of 1800 qubits. Here the multipartite approach shows better scaling for low error rates. Difference in obtainable output copies msg − mbip with a fidelity of at least 0.9 by the shifted grid architecture msg (A) and the bipartite approach mbip (B, C).
