By numerically solving the Sch6dinger equation of a three-nuclear-spin system, the effects of the non-uniform nearest-neighbor （NN） interaction on the fidelity of a quantum controlled-controlled-no （CCN） gate are investigated for a digital initial state and a superposition initial state respectively. It is found from our simulation that the ratio of the deviation of the NN coupling δJ to the NN coupling J should be smaller than 0.0005 to ensure a high fidelity of the quantum CCN gate.

忽略装卸作业、集卡短驳、空箱调运和能源生命周期排放会显著低估铁路运输链的CO_2排放量.本文聚焦国际集装箱内陆段运输,基于运输链视角和能源生命周期理念,研究铁路运输链(自空箱装车至港口重箱卸车)的CO_2排放.根据ASIF(活动—结构—能耗强度—排放因子)方程,建立国际集装箱内陆段铁路运输链的CO_2排放估算模型,并以义乌经宁波港域出口集装箱铁路运输为例,估算不同情景下铁路运输链的CO_2排放量.结果表明,义乌—宁波铁路运输链的CO_2排放量最多被低估99.215%,新建铁路最多可减少CO_2排放量22.821%.研究成果可为评估多式联运的CO_2减排效果提供技术支撑.

本文以具有非对称性自旋相互作用的三体自旋系统为研究对象,重点研究了三体量子相干含时演化规律.采用精确量子对角化和基于量子主方程的数值模拟方法,讨论了三体量子系统中多种量子相干组分及其退相干.研究发现,量子相干组分的含时演化与整个系统的初态量子特性紧密相关.当初态为可分离纯态时,在较短时间内,非对称相互作用有利于增加多体量子相干度.这些量子相干度因受噪声影响而逐渐衰减.当初态为类Werner态时,量子相干度的分布满足加和性,即三体量子相干度等于所有两体量子相干度之和.自旋之间非对称相互作用和环境噪声都会引起三体量子相干度大于所有两体量子相干度之和.这些结论有助于多体量子资源的制备.

中国工业化进程中的投资失调所导致的就业-产业结构失衡是工业产能过剩的重要原因。本文基于中国2002—2016年的省级面板数据,采用差分GMM估计方法检验了就业-产业结构协调发展影响工业产能过剩的直接效应及产业结构、人力资本与技术进步的调节效应,并分析了直接效应和调节效应的门槛效应。研究发现:①就业-产业结构协调发展对工业产能过剩具有显著的化解效应,但呈现“倒U型”的影响路径。②调节效应的结果显示,非效率的产业结构升级与有偏的技术进步升级抑制了就业-产业结构协调发展对工业产能过剩的化解效应,而人力资本升级不仅促进了就业-产业结构协调发展对工业产能过剩的化解效应,还能有效改善了就业-产业结构对化解工业产能过剩的不利影响。③门槛效应的结果表明,随着经济发展阶段的变迁,就业-产业结构协调发展对工业产能过剩的化解呈现“先促后抑”的影响路径,而技术进步升级在跨过经济发展门槛值前后,则呈现出“先抑后促”的影响路径。以上研究结论意味着,现阶段促进就业-产业结构协调发展与加快人力资本升级,可以成为化解工业产能过剩的新思路。
