机构:量子计算正加速从实验验证走向商业化应用
Zheng Quan Shi Bao Wang· 2025-11-18 00:46
中金公司(601995)认为,量子计算作为新一轮科技革命与产业变革的前沿方向,正加速从实验验证走 向商业化应用。随着全球科技巨头(谷歌、IBM、微软等)不断突破量子比特规模与纠错精度,中国 在"祖冲之""九章"等原型机实现多点超越,ICV预计全球量子计算市场规模在2024—2035年由50亿美元 增长至8000亿美元以上。其中,硬件环节先行受益,测控系统、稀释制冷机等核心设备有望早日进入量 产周期。中金公司判断,量子计算正处于由科研突破向商业落地的关键拐点,硬件环节或将率先实现产 业化突破。 国泰海通证券认为,1)量子计算处于早期突破阶段,量子纠错是关键。当前,量子计算已成为最具颠 覆性的前沿技术之一,并逐渐形成集基础科研、工程研发、应用探索和产业培育为一体的发展格局。 2)中国在QKD量子安全领域处于绝对领先地位。量子安全的实现路径一般包括基于数学的传统路径 (PQC)和物理安全路径(QKD)两类。中国已经形成了以QKD技术为核心的较为完整的量子保密通 信产业链。3)量子测量产业进入多元化发展周期。量子精密测量主要是利用量子状态对环境的高度敏 感,提升对时间、位置、加速度、电磁场等物理量的测量精度,涉及的方 ...
重大转变!“中国:0→47%,美国:88%→9%”
Guan Cha Zhe Wang· 2025-11-18 00:44
【文/观察者网 柳白】一边是从0到47%的飞跃,另一边是从88%到9%的暴跌,中美遥感研究论文产出 占比的一升一降,见证了中国遥感技术实力从"起跑"到"领跑"的突破。 香港英文媒体《南华早报》11月18日发文指出,一项最新的研究显示,中国数十年来国家层面持续的大 规模资金投入,已将地球观测科学的主导权从美国夺走。不仅是相关领域的论文研究,中国在专利方面 同样占据全球主导,且在量子计算等相关新技术领域持续投入,实现了纳米级空间测距等技术突破。业 内人士表示,除非美国大幅调整政府资金优先级,否则短期内难以重获该领域的创新领导地位。 2015年,纽约大学教授黛布拉·莱弗坐在布鲁克林的办公桌前,审阅着又一叠遥感领域的研究论文。浏 览到作者所属机构时,她愣住了,那些曾经满是美国大学和美国国家航空航天局(NASA)实验室署名 的期刊,如今已开始刊登来自北京、武汉和上海的研究成果。 在接下来的几年里,最初的涓涓细流逐渐汇成浪潮,而后演变为一场"海啸"。 文章说,回溯20世纪90年代,美国在遥感领域的主导地位,堪比如今硅谷在软件行业的统治力。当时的 美国机构贡献了该领域近90%的研究成果,而中国的相关论文几乎为零。 但到20 ...
事关美股QDII,头部公募集体发声
Jing Ji Wang· 2025-11-18 00:21
11月17日,多家公募集体发布公告,提示美股QDII产品存在溢价风险。 在美股市场单边逞强背景下,散户和游资纷纷拥抱美股主题QDII,并使此类QDII的二级市场价格与基 金净值之间出现大幅溢价。17日,易方达基金、广发基金、景顺长城基金、大成基金、华夏基金等公司 同时发布公告,提示投资者关注二级市场交易价格溢价风险,如果高溢价买入,可能面临较大损失,基 金公司也可能通过申请盘中临时停牌、延长停牌时间等方式,向市场警示风险。 券商中国记者注意到,虽然今年许多美股QDII基金涨幅相对保守,但吸金能力远超港股QDII。例如, 截至11月17日,易方达纳斯达克100QDII基金年内收益率约17%,但该QDII的资产规模从今年1月初的 14亿元,已迅速增长到今年9月末的37亿元。相比之下,许多港股QDII基金虽然在今年取得超50%、 60%甚至90%的好收益,但吸引散户资金的申购能力不足,不少今年业绩排名优异的港股QDII基金,出 现叫好不叫座的现象。 或亦因美股QDII年内涨幅相对保守,在美股QDII未来或出现更好收益率的预期下,在二级市场上,不 少游资和散户资金开始炒作这类QDII的交易价格,从而在交易价格与净值之 ...
