    "abstract": "Decoherence is studied in an attractive proposal for an actual implementation\nof a quantum computer based on trapped ions. Emphasis is placed on the\ndecoherence arising from the vibrational motion of the ions, which is compared\nwith that due to spontaneous emission from excited states of the ions. The\ncalculation is made tractable by exploiting the vast difference in time scales\nbetween the vibrational excitations and the intra-ionic electronic excitations.\nSince the latter are several orders of magnitude faster, an adiabatic\napproximation is used to integrate them out and find the inclusive probability\nP(t) for the elec- tronic state of the ions to evolve as it would in the\nabsence of vibrational coupling, and the ions to evolve into any state\nwhatsoever. The decoherence time is found at zero temperature and for any\nnumber of ions N in the computer. Comparison is made with the spontaneous\nemission decoherence, and the implications for how trap voltages and other\nparameters should be scaled with N are discussed.",
