Quantum many-electron simulation: from correlated mean-field to quantum computing

Tran Nguyen Lan

University of Science, VNU-HCM

For quantum many-body problems, it is crucial to have methods that strike a balance between accuracy and computational costs. Quantum computing is an emerging technology that is expected to tackle issues unsolvable by classical computing. Unfortunately, quantum computing is not yet fully practical due to the current limitations of quantum hardware, and the current state of quantum computing is referred to as the noisy intermediate-scale quantum (NISQ) era. Thus, quantum-classical hybrid approaches have been actively developed to bring quantum computing into realistic applications. In this talk, I will first discuss our current work on correlated mean-field theory (CMFT) for many-body problems in both molecules and solids. I will then present our recently developed downfolding framework derived from CMFT to facilitate variational quantum eigensolver (VQE) in quantum simulation of molecules and solids.
