Classical reservoir approach for efficient molecular ground state preparation
Zekun He, Dominika Zgid, A. F. Kemper +1
Ground state preparation is a central application of quantum algorithms for electronic structure. We introduce the classical reservoir approach, a low cost variational ansatz tailo…

Efficient Fermi-Hubbard model ground-state preparation by coupling to a classical reservoir in the instantaneous-response limit
Zekun He, Lorenzo Del Re, A. F. Kemper +1
Preparing the ground state of the Fermi-Hubbard model is challenging, in part due to the exponentially large Hilbert space, which complicates efficiently finding a path from an ini…
