<正>译者的话双光子纠缠实验,是自20世纪70年代开展以来,验证贝尔不等式、证明量子力学非局域性的主要实验。法国科学家阿兰·阿斯佩(Alain Aspect)在20世纪80年代做了第一个数据令人信服的实验,获得了2022年诺贝尔物理学奖。2000年底,阿兰·阿斯佩在维也纳举行的纪念约翰·贝尔的会议上做了演讲,非常详细地介绍了当年他设计实验的过程(ar Xiv:quant-ph/0402001),其中有些内容是关于实验的思考,至今仍然非常有启发性,经原作者授权,特将此文翻译成中文,以飨广大国内读者。 相似文献

A method that uses radio frequency (RF) spectroscopy to evaluate the alignment of an optical lattice is proposed and demonstrated. A one-dimensional (1D) optical lattice is applied along the long axis of a cigar-shaped Bose-Einstein condensate (BEC) in a magnetic trap. The RF spectra of condensates with and without the optical lattice are analyzed, measured, and compared with the condition in which the lattice is misaligned with the BEC. The proposed method greatly optimizes the optical alignments of the lattices. 相似文献

A laser power feedback control system that features fast response,large-scale performance,low noise,and excellent stability is presented. Some essential points used for optimization are described. Primary optical lattice experiments are given as examples to show the performance of this system. With these performance characteristics,the power control system is useful for applications in cold atom physics and precision measurements. 相似文献
