Abstract
We propose the use of stimulated Raman adiabatic passage to offer a fast high fidelity method of performing SU(2) rotations on spinor Bose-Einstein condensates (BECs). Past demonstrations of BECs optical control suffer from difficulties arising from collective enhancement of spontaneous emission and inefficient two-photon transitions originating from selection rules. We present here a scheme which allows for arbitrary coherent rotations of two-component BECs while overcoming these issues. Numerical tests of the method show that for BECs of with up to atoms and gate times of , decoherence due to spontaneous emission can be suppressed to negligible values.
