Semi-classical Schr odinger FTol Num [JLL22]. The semi-classical regime of the Schr odinger equation corresponds to the case when (cid:126) (cid:28) 1. Possible applications include: quantum chemistry, including Born-Oppenheimer molecular dynamics and Ehrenfest dynamics. Time-dependent Schr odinger NISQ [Jou22] FTol Num [JLL22]. Many problems can be mapped to the Schr odinger equation
