Abstract: When the Coulomb potential is considered,a set of exact solutions of Schr?dinger equation are obtained based on two trapped cold ions in a two-dimensional ion trap.Discrete eigenstates and eigenenergies indicate that the radial motion quantum number is changed in an integral multiple of 1/2,fermions and bosons appear alternately,the motion of mass center magnetic quantum number mc and relative motion magnetic quantum number m make the quantum state generate a stochastic phase factor mcβ+mθ.Taking several states with cold two H+ as examples,a kind of ways of quantun coding by quantum state are obtained.In quantum information processing,utilizing  discrete eigenstates  ψnc,mc,l,m is generated in order to realize the quantum information reading and writing by phase change.

Key words: ion trap, quantum state, trap frequency, phase change
