耗散条件下完整量子计算的重聚焦方案
Refocusing schemes for holonomic quantum computation in presence of dissipation
摘要:
在量子跳跃方法中分析了耗散对完整量子计算方案的影响。我们扩展到非阿贝尔的情况下,以前介绍的(阿贝尔)几何计算的重聚焦策略。我们展示了如何双循环对称化计划,让一个摆脱不必要的影响耗散在无跳跃轨迹。
英文摘要:
The effects of dissipation on a holonomic quantum computation scheme are analyzed within the quantum-jump approach. We extend to the non-Abelian case the refocusing strategies formerly introduced for (Abelian) geometric computation. We show how double loop symmetrization schemes allow one to get rid of the unwanted influence of dissipation in the no-jump trajectory.
