Real-Time Evolution for Ultracompact Hamiltonian Eigenstates on Quantum Hardware
In this work we present a detailed analysis of variational quantum phase estimation (VQPE), a method based on real-time evolution for ground- and excited-state estimation on near-term hardware. We derive the theoretical ground on which the approach stands, and demonstrate that it provides one of the...
