Generation of motional Fock states of a trappedion in the mediate-excitation regime

摘要

We propose a scheme to prepare Fock states for the vibrational motion of a trapped ion. Unlike previous schemes,the present scheme works in the mediate-excitation regime, in which the corresponding Rabi frequency is equal to the trap frequency. Thus, the required time is greatly shortened, which is important in view of decoherence.
