A Kernel-Based Density of States Estimator for Quantum Computing
The Rodeo algorithm is shown to provide a direct quantum analogue of the kernel polynomial method, derive the estimator and its uncertainties, establish an explicit dictionary between signal-processing window functions and quantum reconstruction kernels, and validate the method on the one-dimensional transverse-field Ising and spin-1 models.
