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 Rb87 with up to 104 atoms and gate times of 1μs, decoherence due to spontaneous emission can be suppressed to negligible values.
