Promise of Graph Sparsification and Decomposition for Noise Reduction in QAOA: Analysis for Trapped-Ion Compilations
Graph sparsification and decomposition reduce worst-case H_Ising pulses from O(n²) to O(n log(n/ε)) and Pauli-X flips from O(n²) to O(n log(n/ε)/ε²) for (1-ε) Max-Cut approximation in trapped-ion QAOA compilations.
