Quantum Computed Green's Functions using a Cumulant Expansion of the Lanczos Method
Gabriel Greene-Diniz, David Zsolt Manrique, Kentaro Yamamoto +5
In this paper, we present a quantum computational method to calculate the many-body Green's function matrix in a spin orbital basis. We apply our approach to finite-sized fermionic…
