The Swiss Army Knife of Applied Quantum Technology (Experimental Tech)

Spectral explainability toolkit for quantum-assisted PINNs. It uses Fourier analysis to show how encoding and circuit depth shape a QAPINN's expressivity, pairs that with gradient-variance diagnostics to expose trainability costs, and turns both into a design methodology for choosing quantum layer architectures per PDE class. See README.
