Quantum computers still struggle with chemistry’s hardest molecular calculations

One of the biggest promises of quantum computing is the ability to simulate molecules with unprecedented accuracy. If quantum computers could do this efficiently, this may speed up the discovery of new medicines, batteries, and fertilizers. However, a new theoretical study suggests that the road to this promise is much longer than many researchers had hoped. Through their analysis, the study authors show that even the most popular quantum algorithms face serious obstacles when trying to compute the lowest energy state of molecules—a fundamental quantity needed to understand chemical reactions. “Quantum chemistry is envisioned as an early and disruptive application for quantum...
