Postponing the orthogonality catastrophe: efficient state preparation for electronic structure simulations on quantum devices
Norm M. Tubman, Carlos Mejuto-Zaera, Jeffrey M. Epstein +8
Despite significant work on resource estimation for quantum simulation of electronic systems, the challenge of preparing states with sufficient ground state support has so far been…
