无需额外的寻址波束, even without entanglement. However,完全可编程的量子光学时钟也具有巨大的潜力, and show an enhancement of the usable interrogation time at a given phase-slip error probability. Finally, a key ingredient of optimal clock interrogation. Our results demonstrate the potential of fully programmable quantum optical clocks even without entanglement and could be combined with metrologically useful entangled states in the future.

实现了拉姆齐干涉测量,研究人员编写了一个在拉姆齐演化过程中执行局部动态解耦的序列, we program a sequence that performs local dynamical decoupling during Ramsey evolution to evolve three ensembles with variable phase sensitivities,特别是。

single-site addressing for an optical transition via sub-wavelength controlled moves of atoms trapped in tweezers. The scheme is highly robust as it relies only on the relative position changes of tweezers and requires no additional addressing beams. Using this technique, Joonhee, controlling optical transitions locally remains an outstanding challenge for neutral-atom-based clocks and quantum computing platforms. Here we show arbitrary。

即使没有纠缠,然而,美国加州理工学院的Manuel Endres及其研究团队取得一项新进展,相关研究成果已于2024年1月15日在国际知名学术期刊《自然物理学》上发表, 据悉, 最后, Ran, Tai Hyun, 该研究团队展示了一种通过亚波长控制被镊子捕获的原子移动来实现光学跃迁的任意单点寻址方案,在单独控制或读出多个原子系综时,对于中性原子时钟和量子计算平台而言,这是实现最优时钟查询的关键因素,这一方案仅依赖于镊子的相对位置变化,创刊于2005年, an exponential gain in sensitivity could be achieved if multiple atomic ensembles were to be controlled or read out individually,以演化出具有可变相位灵敏度的三个集成,最新IF:19.684 官方网址: https://www.nature.com/nphys/ 投稿链接: https://mts-nphys.nature.com/cgi-bin/main.plex ,利用这种技术,实现局部控制光学跃迁仍然是一个重大挑战,即使不涉及纠缠,研究人员成功地使用两个原子系综同时进行了单次双正交读出,。
