Laser trapping of ions and asymptotic minimization of Decoherence

摘要

Decoherence time has been calculated for an optical ion trap of Be atoms in abistable potential model. Comparison has been made between decoherence time andZeno time for double well potential as a special case. Zeno time is consideredas a lower limit of decoherence time for sustainable quantum coherence.Equality of the respective timescales provides a certain transitionaltemperature, below which decoherence can be asymptotically minimized.
