Temperature Effect on Cirac and Zoller Model Using Two-Time Green's Function
Wei Li, Zhao Hong-min, Jia-tih Lin · Modern Physics Letters B · 2003
Using the two-time Green's function method, we analyze the temperature effect on the famous Cirac and Zoller model. Formulas for the average number of different mode phonons and the deviation of its internal state from its ground state are derived. The influence of the internal state energy and trap frequency on the number of phonons is also discussed. The upper limit of temperature for regular quantum computation in the Cirac and Zoller model is obtained.
