摘要:
我们提出了一种有效的准确定性方案来产生两个原子系综的最大纠缠态。该方案是基于总原子布居的量子非破坏测量和绝热量子反馈的测量输出的条件。该计划的高效率进行了测试,并确认数值理想的光电探测,以及在存在的损失。
英文摘要:
We introduce an efficient, quasideterministic scheme to generate maximally entangled states of two atomic ensembles. The scheme is based on quantum nondemolition measurements of total atomic populations and on adiabatic quantum feedback conditioned by the measurements outputs. The high efficiency of the scheme is tested and confirmed numerically for ideal photodetection as well as in the presence of losses.
