摘要
We proposed an unconventional Landau-Zener-Stuckelberg interferometry in strongly driven two-level systems subjected to quantum noise. A general transition rate for consecutive Landau-Zener transitions was obtained, from which we could analytically calculate interference fringes. The strong low-frequency noise would detour the evolution paths, leading to asymmetric transition rates which caused unpredicted position shift of the fringes and population inversions in a two-level system.
