We show that strong coupling in quantum plasmonics can be used to mediate efficiently and in a robust way the interaction between emitters when the dynamics is driven along a dark state immune to the strong plasmon loss. This is achieved via a stimulated Raman adiabatic passage induced by laser pulses driving the emitters. We develop, from a fully quantized Hamiltonian of surface plasmons based on the Green tensor, a general toolbox which allows one to derive effective multimode models. Highly efficient and robust population transfer, as well as the deterministic generation of entanglement between emitters are numerically shown. These results pave the way for an efficient use of the quantum plasmonic platform beyond its inherent losses.
