Quantum adiabatic evolution is not necessary adiabatic: Adiabatic
evolution realized by dynamical decoupling [PDF]
Zhen-Yu WangWe analyze the conditions that lead to an adiabatic evolution with a geometric phase accumulated. To realize the adiabatic evolution, the instantaneous eigenenergies and the degeneracy of the Hamiltonian can change rapidly during the evolution. Using pulse sequences or fast modulation fields, we can suppress the state transitions and realize the adiabatic evolution in a much shorter time.View original: http://arxiv.org/abs/1210.4323
