Oscillations in a Landau-Zener Transition

POSTER

Abstract

Landau-Zener transition has been explored in varieties of systems and becoming more and more applicable especially in the developing quantum information processing. But the effects of finite sweeping range in the vicinity of an avoided energy-level crossing is lack of experimental evidence. Here we experimentally proved the inapplicability of the Landau-Zener formula in the vicinity of an avoided energy-level crossing and demonstrated two anomalous oscillations in the Landau-Zener transition, which agree well with the numerical simulations. Our results not only provide a closer view of Landau-Zener transition but also shed light on its application in the quantum state manipulation.
