首张量子纠缠图像问世!
今年早些时候,人类首次拍到了黑洞的照片,当时全球都轰动了起来。
而现在,一个同样重要的事件发生了!
据物理学家组织网近日报道,英国物理学家首次拍摄到一种量子纠缠的照片,捕获到这种难以捉摸现象的视觉,最新研究有望促进量子计算等领域的发展。

Einstein described quantum mechanics as “spooky” because of the instantaneousness of the apparent remote interaction between two entangled particles.
爱因斯坦说量子力学很“诡异”,因为两个相距明显很远的纠缠粒子瞬间就能相互作用。
The interaction also seemed incompatible with elements of his special theory of relativity.
这种相互作用好像也和他狭义相对论的元素相矛盾。
Scientist John Bell later formalised the concept by describing in detail a strong form of entanglement exhibiting the feature.
后来科学家约翰·贝尔通过详细描述一个表现出该特性的强纠缠形式来使这一概念形式化。
Bell entanglement is now harnessed in practical applications such as quantum computing and cryptography.
贝尔纠缠现在被用于多个实际应用,如量子计算和密码学。
However, it has never before been captured in a single image.
但此前它从未被捕捉到单一图像。
图灵将在2021年登上英镑钞票
计算机科学之父艾伦·图灵终于要登上英镑了。
知道内情的人应该都懂,这不光是对一位科学伟人的致敬,还有很多深层的含义。
这位被历史亏待、牺牲,最后不得善终的天才,得到了一次公开的道歉。

Alan Turing, the father of computer science and artificial intelligence who broke Adolf Hitler’s Enigma code system in World War II will be featured on the Bank of England's new 50-pound note.
艾伦·图灵被称为计算机科学之父,人工智能之父,他在二战中破译了阿道夫·希特勒的Enigma密码系统。他的头像将出现在英格兰银行新发行的50英镑纸币上。
It’s expected to enter circulation by the end of 2021. It will include a quote from Turing: “This is only a foretaste of what is to come and only the shadow of what is going to be.”
新纸币预计于2021年底开始流通,纸币上还会引用图灵的名言:“这不过是将来之事的前奏,也是将来之事的影子。”

The 2019 superhero blockbuster, originally released globally in April, finally surpassed the global ticket sales of James Cameron’s sci-fi film Avatar, which had held the record since 2009.
这部2019年的超级英雄大片最初于4月份在全球上映,最终全球总票房超过了詹姆斯·卡梅隆的科幻片《阿凡达》,自2009年起《阿凡达》一直保持着票房纪录。
All in all, Endgame has grossed $2.79 billion at the global box office, besting Avatar’s total by only about $1 million.
《复联4》全球总票房27.9亿美元,只超过《阿凡达》约100万美元。
Avatar needed a mere 41 days to beat the previous record holder, Titanic (also directed by Cameron), while it took Endgame 85 days to get past Avatar.
《阿凡达》仅用41天就打败了之前的纪录保持者《泰坦尼克号》(也是卡梅隆执导的影片),而《复联4》却用了85天才超过《阿凡达》。
