In this talk, I will describe a new hybrid algorithm, quantum-classical hybrid quantum Monte Carlo (QC-QMC), that has demonstrated accurate quantum computations of chemical systems beyond what has been possible with other variational NISQ algorithms. I will explain what algorithms need to consider when showing practical quantum advantages and why QC-QMC has attractive features. I will also remark on challenges in QC-QMC that must be considered when designing one of the first demonstrations for quantum advantage in chemistry. This talk is meant to engage both chemistry and quantum information science audiences as the synergistic interactions between the two are critical.
