Requirements for building effective Hamiltonians using quantum-enhanced density matrix downfolding
Shivesh Pathak, Antonio E. Russo, Stefan Seritan +4
Density matrix downfolding (DMD) is a technique for regressing low-energy effective Hamiltonians from quantum many-body Hamiltonians. One limiting factor in the accuracy of classic…

Quantifying -gate-count improvements for ground-state-energy estimation with near-optimal state preparation
Shivesh Pathak, Antonio Russo, Stefan Seritan +1
We study the question of when investing additional quantum resources in preparing a ground state will improve the aggregate runtime associated with estimating its energy. We analyz…
