摘　　要：The behavior of quantum cellular automata （QCA） under the influence of a stray charge is quantified. A new time-independent switching paradigm, a probability model of the double-dot system, is developed. Superiority in releasing the calculation operation is presented by the probability model compared to previous stray charge analysis utilizing ICHA or full-basis calculation. Simulation results illustrate that there is a 186-nm-wide region surrounding a QCA wire where a stray charge will cause the target cell to switch unsuccessfully. The failure is exhibited by two new states＇ dominating the target cell. Therefore, a bistable saturation model is no longer applicable for stray charge analysis.The behavior of quantum cellular automata （QCA） under the influence of a stray charge is quantified.
