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…

Self-healing of Trotter error in digital adiabatic state preparation
Lucas K. Kovalsky, Fernando A. Calderon-Vargas, Matthew D. Grace +4
Adiabatic time evolution can be used to prepare a complicated quantum many-body state from one that is easier to synthesize and Trotterization can be used to implement such an evol…
