Abstract
It has been proposed that the adiabatic loading of a Bose-Einstein Condensate into an optical lattice via the Mott-Insulator transition can be used to initialize a quantum computer [D.Jaksch, et al., Phys. Rev. Lett. 81, 3108 (1998)]. The loading of a Bose-Einstein Condensate into the lattice without causing band excitation is readily achievable; however, unless one switches on an optical lattice very slowly, the optical lattice causes a phase to accumulate across the condensate. We show analytically and numerically that a cancellation of this effect is possible by adjusting the harmonic trap force-constant of the magnetic trap appropriately, thereby facilitating quick loading of an optical lattice for quantum computing purposes. A simple analytical theory is developed for a non-stationary BEC in a harmonic trap.
