英文摘要：
Shannon entropy in position ($S_{\rvec}$) and momentum ($S_{\pvec}$) spaces, along with their sum ($S_t$) are presented for unit-normalized densities of He, Li$^+$ and Be$^{2+}$ ions, spatially confined at the center of an impenetrable spherical enclosure defined by a radius $r_c$. Both ground as well as some selected low-lying singly excited states, \emph{viz.,} 1sns (n $=$ 2-4) $^3$S, 1snp (n $=$ 2-3) $^3$P, 1s3d $^3$D are considered within a density functional methodology that makes use of a work-function-based exchange potential along with two correlation potentials (local Wigner-type parametrized functional as well as the more involved non-linear gradient- and Laplacian-dependent Lee-Yang-Parr functional). The radial Kohn-Sham (KS) equation is solved using an optimal spatial discretization scheme via the generalized pseudospectral (GPS) method. A detailed systematic analysis of the confined system (relative to corresponding free system) has been performed for these quantities with respect to $r_c$ in tabular and graphical forms, \emph{with and without} electron correlation. Due to compression, the pattern of entropy in aforementioned states gets characterized by various crossovers at intermediate and lower $r_c$ regions. The impact of electron correlation is more pronounced in weaker confinement limit, and appears to decay with rise in confinement strength. The exchange-only results are quite good to provide a decent qualitative discussion. The lower-bounds provided by entropic uncertainty relation holds good in all cases. Several other new interesting features are observed.

Single-ion addressing via trap potential modulation in global optical fields
迄今为止，离子量子位的单独寻址主要依赖于经由电磁场空间梯度或经由离子传输操作产生的离子之间的局部拉比或跃迁频率差。或者，可以通过利用全局驱动场中的局部相位差来合成任意局部单量子比特门。在这里，我们报告了使用全局门激光场中的轴向势调制在双离子晶体中对$^{40}$ Ca $^+$离子的单独寻址。我们通过一个量子位随机基准测试，对每个共同捕获的离子应用不同的随机序列来表征所得到的门性能。我们确定了主要的误差来源，并将结果与单离子实验进行比较，以更好地了解我们的实验局限性。这些实验形成了一个基础的通用控制的两个离子，限制在同一个势阱，与一个单一的门激光束。
