Comparing Classical and Quantum Ground State Preparation Heuristics

Understand

One promising field of quantum computation is the simulation of quantum systems, and specifically, the task of ground state energy estimation (GSEE).

• Ground state preparation (GSP) is a crucial component in GSEE algorithms, and classical methods like Hartree-Fock state preparation are commonly used.
• However, the efficiency of such classical methods diminishes exponentially with increasing system size in certain cases.
• In this study, we investigated whether in those cases quantum heuristic GSP methods could improve the overlap values compared to Hartree-Fock.
