We propose the use of stimulated Raman adiabatic passage (STIRAP) to offer afast high fidelity method of performing SU(2) rotations on spinor Bose Einsteincondensates (BEC). Past demonstrations of BEC optical control suffer fromdifficulties arising from collective enhancement of spontaneous emission andinefficient two-photon transitions originating from selection rules. We presenthere a novel scheme which allows for arbitrary coherent rotations oftwo-component BECs while overcoming these issues. Numerical tests of the methodshow that for BECs of \ce{^{87}Rb} with up to $ 10^4 $ atoms and gate times of$ \SI{1}{\micro\second} $, decoherence due to spontaneous emission can besuppressed to negligible values.
