Optimized non-uniform shot allocation guided by an equation-of-motion error cost function reduces measurement overhead by >2x and improves fidelity in noisy imaginary-time VQDS for 1D Ising ground states.
Quantum regression encodes data tables into quantum states with variational parameters as direct regression coefficients, enabling interpretability, reduced gate complexity, and cost function measurements aligned with mean squared error.
Optimized q-sc-EOM on quantum hardware yields accurate excited-state energies for challenging molecular bond-breaking cases after reducing measurement scaling to O(N^5) and applying readout and symmetry error mitigation.
