A record-breaking experiment by a Chinese satellite has taken the weird world of quantum physics to new heights and is likely to spur other nations including Canada in their efforts to develop an unhackable form of long-distance communication

中国卫星一个破纪录的实验将量子物理学的奇异世界带到了一个新高度，并有可能激发包括加拿大在内的国家努力发展一种不可破解的远距离通信模式。

“We have done something that was absolutely impossible using conventional approaches” said Jian-Wei Pan project leader and physicist at the University of Science and Technology of China in Hefei. Dr. Pan suggested his team’s achievement had “kick-started a new quantum space race.”

“我们已经完成了一些用传统手段绝对无法完成的事情”项目带头人，坐落于合肥的中国科学技术大学物理学家潘建伟说到。潘博士说他们团队的成就“引发了新一轮的量子空间竞赛。”

The tour de force experiment featured a device on the satellite beaming pairs of photons – individual particles of light – lixed by a mysterious effect known as quantum entanglement to two separate receiving stations on Earth. The stations were located 1203 kilometres apart a tenfold increase in distance over ground-based tests. Because such quantum signals are effectively impervious to eavesdropping the results have implications for efforts to create more secure communication networks.

这个精湛的实验的特色是卫星上的一个装置辐射光子对——单个粒子的光。这对光子被一种叫做“量子纠缠”的神秘效应联系在一起，分别被两个地球基站接收。两个基站相距1203公里，这比地面实验距离提升了10倍。这种量子信号具有高度抗窃听性，因此实验结果对创造更安全的通信网络具有重要影响。

“I believe this will lead to an increase of interest in other countries to follow up” said Thomas Jennewein a researcher at the University of Waterloo who called the Chinese result the “first proof of concept” for satellite-based quantum communications.

“我相信这会增加其他国家跟进的兴趣，”滑铁卢大学研究员Thomas Jennewein 说，他将中国的成果称为卫星量子通信概念的“首次证明”。

No "not canada" but we are in the game and if nothing else this is an illustration of why we need open borders and international co-operation if we are to stay in the game. By we I mean the West and I mean particularly the United States of America. Their protectionism means going backward on every front.

确实不是加拿大的，但是我们也是这场游戏的参与者，如果没有别的办法，而且如果我们想留在这个游戏中我们就必须开放边界进行国际合作。西方国家特别是美国的保护主义政策将使我们的方方面面都在倒退。

@Tormaine Needham originally planned to write a book cataloguing Chinese inventions but his first volume barely scratched the surface of his subject. He slowly gatherred many of his students into this enterprise and they eventually wrote a collection of 26 books to catalog the history of Chinese discovery.
Myth and Misrepresentation
It leaves one speechless to learn the vast extent of things invented by the Chinese many hundreds of years and often several millennia before they appeared in the West.

回复@Tormaine ：Needham(李约瑟，英国近代生物化学家和科学技术史专家) 本打算写一本中国发明编目表，然而他发现第一卷作品仅触及皮毛。他慢慢召集学生参与这项工程，最终写了一套26本编目中国历史发明的巨着——《中国科技史》。
这本书使人见识了中国人早在西方几百甚至上千年前就发明的大量东西，让人无言以对。

— Tormaine
That is a statement that bears no merit. Do you not think that other countries including the US and Canada are not doing any industrial espionage.
Science BTW tends to be shared. Not everything can be tagged and priced to meet the pursuit of happiness model.

回复Tormaine的“他们从谁那儿偷的？”
这是毫无价值的发言。你是不是觉得其他国家，包括美国和加拿大就不搞工业间谍活动了？顺便说一句，科学的本质在于分享。不是所有东西都能被贴上价格标签，好满足对幸福模式的追求。

Fascinating work and a job well done to China. Their picking up of the baton in science technology and space exploration will advance humanity even further. I cant say if this is a small step or a giant leap but their space programs will be very interesting to watch in future.

令人着迷的工作，中国干得好！他们正在接过科技研究和空间探索的接力棒，将使人类进步。我可以说，不管这是一小步还是一大步，未来他们的空间项目将会非常有趣。

Now if you are for oppressive dictatorships then yes it is good news.

这会在日本入侵时提供许多帮助。

Why is Canada wasting research dollars trying to help develop this? The government will just promote it to and allow it to be sold out to the Chinese or highest bidder.

为什么加拿大要浪费研究经费协助这个研究？政府将会允许、促使把它卖给中国人或出价最高者。

Research isn't protected in the sense that technology is. I guess following your argument all research would be a total waste including curing life threatening disease and fighting global warming since anyone in the world is free to make use of research results. You might have to shell out a few bucks for the journals and research papers but that is all. Well other than the 10-20 years getting the post-graduate education so that you can understand what you are reading. Note that the Chinese also share their research results with us.

研究不像技术那样受(专利)保护，按你的理论，所有的研究都是浪费，包括应对生活的各种威胁——疾病、全球变暖等，因为所有人都可以免费使用研究成果——当然啦，学术期刊和研究报告可能要花上点儿钱去买，不过想读懂这些，你还需要接受10~20年的教育。记住，中国人同样在向我们分享研究成果。

Well considering how behind Canada is... they ain't selling them nothing.
Heck the Chinese are going to give away this new research anyways like they always have in Quantum physics.
We can't even build a gawd dang train....while China has the largest high speed rail network in the world. Canada has very little to offer them when it comes to intelligence.
Only reason Canada even comes close to China's test scores is cause of Chinese immigrants. Canadians particularly white people in this country consistently score below average. That Vancouver based satellite company likely employs Chinese temporary foreign workers to do all the research and development. But wait... we can stick a pipe into the ground and pump out the black stuff. That's our only value added. The irony is it ain't the ivory tower pumping that oil out. Its trashy red necks doing all the heavy lifting.

回复楼上的“为什么加拿大要浪费钱参与”：
然而，加拿大太落后了，他们没啥可卖的(技术)。
无论如何，中国人就要发表这个新研究了，他们在量子物理领域处于领先地位。
我们甚至造不出一列该死的火车，而中国有全球最大的高铁网，加拿大实在没啥智力成果能提供给他们的。
加拿大能接近中国成绩的唯一原因是中国移民，长期以来，加拿大本地人尤其是白人成绩低于平均值。温哥华的卫星公司喜欢雇佣中国人和外国临时工来做所有的研究发展工作。
等等……我们不是还能挖石油吗？这可是我们唯一的价值了，然而讽刺的是，挖石油的不是高级人才，全是乡巴佬在干这些体力活。

It may not be possible to hack quantum communication but there's a catch as anyone try to hack the massage it will automatically destroy it that's means anyone with basic skill of hacking can just try NOT to steal the massage but destroy it by constant hacking the communication to disable the whole system. So I don't think it's a great deal after all.

虽然不太可能窃取量子通讯，但是如果有人试图窃取信息，信息就会被自动毁掉。这意味着，虽然无法获取信息，但任何有基础技术的黑客都可以通过不断入侵通信过程而让整个系统瘫痪。所以我觉得这不是个好想法。

Did you read the article? The point is not to send the "message" itself but to swap encryption keys between 2 points. If the system is compromised just resend the keys until success. Modern cryptography is basically unbreakable (given time constraints) and should depend solely on the encryption keys.

你读文章没？关键点不是传送“信息”本身，而是在两地点之间交换密匙。如果系统被窃听了，那么就重发密匙直到成功。现代密码学是不可破解的(在时间限制内)，而且仅仅依靠密匙。

If we just convicted hackers and made them actually serve time instead of a slap on the wrist then we wouldn't have to spend trillions trying to create unhackable systems.

如果我们严惩黑客，而不是轻微处罚。我们根本就不必花上千亿创造一个牢不可破的系统。
