N2 - The ion trap quantum computer proposed by CIRAC and ZOLLER [Phys. Rev. Lett. 74, 4091 (1995)] is analyzed for decoherence due to vibrations of the ions. An adiabatic approximation exploiting the vast difference between the frequencies of the optical intraionic transition and the vibrational modes is used to find the decoherence time at any temperature T. The scaling of this decoherence time with the number of ions is discussed, and compared with that due to spontaneous emission.
