Input-Data Information Preservation and Protocol-Specific Error Mitigation in Noisy Fixed-Parameter Quantum Front Ends: A Reproducible Simulation Study
I examine whether a noisy fixed-parameter quantum front end preserves class information from input data before variational optimization. Only the input vector <inline-formula> <tex-math notation="LaTeX">$x$ </tex-math></inline-formula> is encoded; the label is used after circuit execution to estimate training distribut...
