Exploring practical methods for detecting k-nonseparability in multipartite quantum states

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 255-256页

作者： Shunlong luo Academy of Mathematics and Systems Science Chinese Academy of Sciences

Quantum entanglement, referred to as “spooky action at a distance” by Einstein, is not only an intriguing and fascinating feature of quantum theory challenging our classical intuitions about locality and correlations, but also has practical and profound implications for quantum technologies. Initially described by Einstein, Podolsky and Rosen, as well as by Schro¨dinger, entanglement now has become a basic and crucial ingredient for both foundational and experimental investigations of the quantum world.

为了能够逼真模拟复杂虚拟环境中大规模群体行为,在国内外相关研究成果基础上提出一种基于分层智能空间环境的群体行为模型建模方法。基本思想是把传统的三维连续地理空间环境分解为一组局部智能空间环境对象,对象中不但存储有约束个体行为模型的基本约束信息,同时还储存有不同个体在环境不同区域可执行的行为信息。这样,虚拟环境中的个体可以在其所处的具体环境提供的信息的约束和指导下进行实时行为合成与决策。仿真实验表明,该方法不仅能够逼真的模拟大规模群体在复杂虚拟环境中的各种规范化行为,而且可以有效减少个体决策模型的计算量,提高模型运行效率。

目的采用心音图运动试验(PCGET)检测和评估正常、足月新生儿出生早期(0~7d)的心力储备(CCR)。方法选择2013年1月1日至2015年1月1日,于成都市妇女儿童中心医院产科住院分娩的1 797例正常、足月的出生早期新生儿为研究对象。根据其出生后不同日龄,将其分为0~7d组(n=192、257、270、214、232、212、210、210)。采用前瞻性研究方法,检测和分析这些新生儿的第一心音(S1)与第二心音(S2)的幅值比值(S1/S2)、心脏舒张期时限(D)与收缩期时限(S)的比值(D/S)和应激后心力变化趋势(CCCTS)。采用Kruskal-Wallis H秩和检验,对8组新生儿安静时和哭泣后的S1/S2,哭泣后的CCCTS分别进行整体比较及组间两两比较。采用方差分析,对8组新生儿安静时和哭泣后的D/S分别进行整体比较,采用最小显著性差异(LSD)法进一步进行组间两两比较。采用配对设计的Wilcoxon符号秩和检验,对8组新生儿安静时和哭泣后的S1/S2进行组内比较;采用配对t检验,对8组新生儿安静时和哭泣后的D/S进行组内比较。采用Spearman秩相关性分析,对这些新生儿安静时的S1/S2与D/S相关性进行分析。采用多重线性逐步回归分析,对纳入研究新生儿安静时D/S的影响因素进行分析。本研究遵循的程序符合成都市妇女儿童中心医院人体试验委员会制定的伦理学标准,得到该委员会批准,分组征得受试儿监护人知情同意,并与监护人签署临床研究知情同意书。结果 (1)8组正常、足月的出生早期新生儿安静时的S1/S2整体比较,差异有统计学意义(χ~2=847.5,P0.05)。(3)8组新生儿哭泣后的S1/S2整体比较,差异有统计学意义(χ~2=7.8,P0.05),但是0~2d组的S1/S2均显著低于3~7d组,并且差异均有统计学意义(P0.05)。(5)0d组新生儿安静时和哭泣后的S1/S2组内比较,差异无统计学意义(P>0.05);但是其余7组则显著低于同组新生儿哭泣后的S1/S2,并且差异均有统计学意义(P<0.001)。(6)8组新生儿安静时的D/S均显著高于组内新生儿哭泣后的D/S,并且差异均有统计学意义(P<0.001)。(7)纳入研究新生儿安静时的S1/S2与D/S呈负相关关系(r_s=-0.1,P<0.001)。(8)对纳入研究新生儿安静时D/S的影响因素进行多重线性逐步回归分析的结果显示,新生儿日龄越大、母亲孕次越少及新生儿性别为男性,其安静时的D/S越大。(9)本研究根据新生儿PCGET检测结果,计算出不同日龄正常、足月的出生早期新生儿安静时和哭泣后的CCR各项指标95%参考值范围。结论通过PCGET检测建立正常、足月的出生早期新生儿CCR评估体系,或许可为我国针对这类新生儿的心脏保健,提供理论依据。

＜正＞are earth ions doped insulators have attracted great interest due to their wide varieties of applications. For these materials, the microstructure of the host is believed to have the crucial impact over their properties. Recently, with the development of new methods of synthesis, characterization and tailoring, people are able to affect the local structure around impurity ions through many artful designs, such as size reduction and surface modification, giving rise to subtle controls over the properties. However, since these approaches do not deal with ultimate change of the microstructure and just bring partial influence to the local environment, the properties improvement achieved is limited. A more simple and direct way to improve the performance of current materials, based on the correlation between microstructure and properties, is to change the structure of the host materials. Despite the simplicity of this idea, few efforts have been made to test and apply it to develop new hosts for functional materials.
