Accelerating an adiabatic process by nonlinear sweeping
曹兴鑫, ZHUANG JUN, 宁西京, 张文献 · 中国物理B：英文版 · 2013
We investigate the acceleration of an adiabatic process with the same survival probability of the ground state by sweeping a parameter nonlinearly, fast in the wide gap region and slowly in the narrow gap region, in contrast to the usual linear sweeping. We find the expected acceleration both in the Landau-Zener tunneling model and in the adiabatic quantum computing model for factorizing the number N = 21.
