Constructs an explicit unitary Q using the quantum Schur transform to coherently map fixed-N first-quantized states to occupation-number form with poly(N,d,log(1/ε)) gate complexity.
Develops a validation framework for quantum spin dynamics simulations anchored by neutron scattering and classical methods, using observable maps, uncertainty propagation, robustness tests, and actuator-aware feedback.
