Captured weight and boundary leakage bound the error of sample-based spectral functions
Nicolás Bonilla Vargas
Rayleigh-Ritz on a subspace from sample-based quantum diagonalization yields the spectral function of a probe state; we ask what bounds its error. The captured Born weight w does n…

Machine learning for sample-based quantum diagonalization: a review of generative configuration recovery and the classical-simulability frontier
Nicolás Bonilla Vargas
Sample-based quantum diagonalization (SQD), equivalently quantum-selected configuration interaction (QSCI), has become a centre of gravity of pre-fault-tolerant quantum chemistry:…
