摘要
Quantum computing gates are proposed to apply on trapped ions in decoherence-free states. As the phase changes due to time evolution of components with different eigenenergies of quantum superposition are completely frozen, quantum computing based on this model would be perfect. Possible applications of our scheme in future ion-trap quantum computers is discussed.
