In this study, we evaluate the effect on ion-trap quantum computers（QCs） from the quantum nature of the driving field, and propose a theoretical limit for ion-trap QCs that may impact the design of quantum algorithms and realization of practical QCs. We obtain, for the first time, the permitted depth of logical operation for fault-tolerant ion-trap QCs. Physically, we provide an exact（full-quantum） description of the QC system, and present for the first time its time evolution after gate operati...
