We study the many-body dynamics of stimulated Raman adiabatic passage in the presence of on-site interactions. In the classical mean-field limit, explored in A. Dey et al. [Phys. Rev. Lett. 121, 250405 (2018)PRLTAO0031-900710.1103/PhysRevLett.121.250405], interaction-induced chaos leads to the breakdown of adiabaticity under the quasistatic variation of the parameters, thus producing low-sweep-rate boundaries on efficient population transfer. We show that for the corresponding many-body system, alternative quantum pathways from the initial to the target state open up at even slower sweep rates. These quantum detours avoid the chaotic classical path and hence allow a robust and efficient population transfer.
