Eats to the heart's content, should do a matter. 酒足饭饱,也该去干点事情了。 For the last link of cislunar control duty chain, a matter of wicker basket waits for him to complete. 为了地月掌控任务链的最后一个环节,还有一箩筐的事情等着他去完成。 However when he is preparing sets out before the desk, outside the office actually suddenly resounded the knock. 然而就在他正准备从办公桌前起身的时候,办公室外却是忽然响起了敲门声。 Thinks appointment in yesterday's telephone, Lu Zhou guessed correctly probably is, threw into the paper goods the pack box conveniently, gripped the plastic bag again puts tightly in one side, clears throat to say. 想到了昨天电话中的预约,陆舟大概猜到了是谁,随手将纸巾扔进了打包盒里,再将塑料袋扎紧搁在了一边,清了清嗓子开口说道。 „Come.” “请进。” The gate of office shoved open, sees only Chief Li that familiar, and did not have the accidental/surprised face to appear in the entrance slightly, saw to put in table nearby pack box, he who prepared to greet with a smile, on the face showed the surprised expression. 办公室的门推开了,只见李局长那张熟悉且没有丝毫意外的脸出现在了门口,看到搁在桌子旁边的打包盒,正准备笑着打声招呼的他,脸上不禁露出了惊讶的表情。 „...... Do you eat this thing at noon?” “……你中午就吃这东西？” Lu Zhou looked at his one eyes strangely. 陆舟奇怪地看了他一眼。 „Does two meat element, have the issue?” “两荤一素,有问题吗？” „, Does not have......” “呃,没有……” „Without said that the matter, around 3 : 00 pm I must return to that side the higher research institute to meet, about the lunar orbit construction committee that side work,” looked at time on the watch, Lu Zhou looked that continued to say to Chief Li, „what matter that you yesterday in the telephone with are I did say?” “没有就说正事儿吧,下午 3 点多我还要回高等研究院那边开个会,关于月球轨道施工委员会那边的工作,”看了眼手表上的时间,陆舟看向李局长继续说道,“你昨天在电话里和我说的到底是什么事情？” Chief Li has not spoken, looked at Wang Peng one. 李局长没有说话,看了王鹏一眼。 Wang Peng nods, takes up the pack box to withdraw from the office knowingly, and took the gate conveniently. 王鹏点了点头,心领神会地拿起打包盒退出办公室,并顺手带上了门。 In the office was only left over two people. 办公室里只剩下了两个人。 Saw not to have others, Chief Li then to say. 见没有了其他人,李局长这才开口说道。 „Matter about that quantum encryption algorithm.” “是关于那个量子加密算法的事情。” Heard is this matter, the eyebrow of Lu Zhou is interested immediately lifts under asked. 一听到是这件事情,陆舟的眉毛顿时感兴趣地抬了下问道。 „Easy-to-use?” “好用吗？” „Easy-to-use! Simply was too easy-to-use.” Chief Li patted starting, haha said with a smile, „you do not know, the deputies of our magnificence Keyuan information engineering research institute after seeing, has almost not knocked the chin surprisedly on the ground......” “好用！简直是太好用了。”李局长拍了下手,哈哈笑着说道,“你不知道啊,咱们华科院信息工程研究所的副所长在看到了之后,惊讶地差点没把下巴磕在地上……” Saw that this fellow is describing delightedly, Lu Zhou always not good premonitions. 看到这家伙眉飞色舞地形容着,陆舟总有一种不太好的预感。 Each time this old man and he does everything to please, is not the plan introduces the object to him, has the matter to trouble him. 每次这老头和他献殷勤,不是打算给他介绍对象,就是有事儿要麻烦他。 „......, since easy-to-use, you also do ask me to do?” “……既然好用,你还来找我干什么？” Chief Li smiles to say. 李局长嘿嘿一笑说道。 „A while ago you did not say, after your carbon base analysis situs quantum processor chip comes out, how long quantum computer couldn't want to break through 1000 Qubit?” “前段时间你不是说,你那个碳基拓扑量子处理器芯片出来之后,要不了多久量子计算机就能突破1000量子比特吗？” Lu Zhou thought a while, selected under. 陆舟想了一会儿,点了下头。 „I good to want truly to say.” “我好想确实说过。” „Is this matter!” Patted under the palm, Chief Li continues saying that „couple days ago in the section met, specifically discussed this issue, but does to us really to lack this expert in aspect, discussed the half of the day cannot discuss a reason why......” “为的就是这件事情！”拍了下手心,李局长继续说道,“前几天部里开会,专门讨论了这个问题,但奈何我们实在缺乏这方面的专家,讨论了半天也讨论不出来个所以然……” „Stops, does not need to give me to explain the cause and effect,” Lu Zhou lifts the hand, stopped the words of Chief Li, sighed saying that „...... you told me also to have any troublesome matter to be good directly.” “打住,不用给我解释前因后果的,”陆舟抬起手,打住了李局长的话,叹了口气说道,“……你直接告诉我又有什么麻烦事儿好了。” „Pouring is not the trouble matter, mainly under wants to consult your opinion,” Chief Li smiles embarrassed, the inquiry said, „...... this 2000 Qubit's computer, when can come out probably?” “倒也不是什么麻烦事儿,主要就是想咨询下您的意见,”李局长不好意思地笑了笑,提问道,“……这个2000量子比特的计算机,大概什么时候能出来？” Hears Chief Li these words, Lu Zhou understands immediately he is thinking anything, did for quite a while in the worry technology time-limited issue. 一听到李局长这句话,陆舟立刻明白他在想什么了,搞了半天是在担心技术时效性的问题。 However is also unavoidable, generally will be individual will have this worry. 不过也难免,一般是个人都会有这种顾虑。 If from 80 to 500 bottlenecks is so easy to break through, was very difficult saying that from 500 to 1000, as well as how long from 1000 to 2000 technological barriers can insist again. 如果从80到500的瓶颈都这么容易突破的话,很难说从500到1000,以及从1000再到2000的技术壁垒又能坚持多久。 Replacement encryption algorithm matter, does not change penguin password small matter, this involves the reform of entire communication domain, the recessive social cost that needs to pay, is hard to be pure with money weighs. 更换加密算法这种事情,可不是改个企鹅密码这种小事儿,这涉及到整个通讯领域的改革,其中需要支付的隐性社会成本,是难以单纯用金钱去衡量的。 If possible, the relevant departments naturally are the hope replace an encryption algorithm, can manage slightly for a long time. 如果可以的话,有关部门自然是希望更换一次加密算法,能管得稍微久一点。 Don't when the time comes 35 years on a renewal encryption algorithm, even financial industry, communications industry and Internet industry China again how tenacious, cannot withstand tosses about...... 别到时候三五年就更新一次加密算法,就算华国的金融行业、通信行业、互联网行业再怎么坚韧不拔,也经不起这么折腾…… „Your worry is actually unreasonable,” the index finger knocked knocking on the table gently, Lu Zhou pondered over a moment later, said, „this gadget was very difficult to say. I can only tell you 1000 Qubit's bottleneck to break through in a short time, but after 2000 Qubit...... at least must wait till 1000 Qubit to break through, I can give you an accurate estimate.” “你的担心倒不是没有道理,”食指在桌上轻轻敲了敲,陆舟思忖了片刻之后,说道,“不过这玩意儿真的很难说。我只能告诉你1000量子比特的瓶颈是可以在短时间内突破,但2000量子比特……至少得等到1000量子比特突破了以后我才能给你个准确的估计。” Chief Li is: „It is estimated that isn't one good?” 李局长为难道:“估计一下都不行吗？” „It is not the issue that the estimate is good, but simply does not have the significance,” Lu Zhou sighed, „you, if only wants to attempt a psychology to comfort, might as well look for telling fortunes asking, was 55 opens from the angle of probability in any case. And......” “不是估计行不行的问题,而是根本没有意义,”陆舟叹了口气,“你要是只想图个心理安慰,不如找个算命的问,从概率的角度反正都是五五开。而且……” , Lu Zhou continued to say. 顿了顿,陆舟继续说道。 „Quantum encryption algorithm forever for a while, what n Qubit corresponds is a 2 ^ n condition, rather than 2 is multiplied by n. Theoretically if only the difficulty of linear pile high proposition, one day our encryption methods, the meeting is unable to catch up with the speed of our information technology development.” “量子加密算法永远只是一时的,n个量子比特对应的是2^n个状态,而不是二乘以n。理论上如果只是线性的堆高命题的难度,总有一天我们的加密手段,会无法追上我们信息技术发展的速度。” In the office fell into silent. 办公室里陷入了沉默。 Is chewing Lu Zhou these words repeatedly, Chief Li pondered long time, crossed the earnest opens the mouth to ask some little time. 反复嘴嚼着陆舟这句话,李局长沉思了良久,过了好一会儿才认真开口问道。 „You felt, what to do should we?” “那您觉得,我们应该怎么办？” „Only can solve this problem fundamentally, after” Lu Zhou thought a while said, „in other words, ceases the possibility of leaking from the communication method!” “只能从根本上解决这个问题,”陆舟想了一会儿之后说道,“也就是说,从通讯手段上杜绝泄密的可能！” „Is your meaning...... the quantum communication?” “您的意思是……量子通信？” The Lu Zhou applause nods. 陆舟赞许地点了点头。 „.” “正是。” The expression of Chief Li is somewhat dignified. 李局长的表情有些凝重。 „......, but I heard, the quantum communication technology isn't simple? Our country in this is also walks front the comparison, the achievement also had much, but I had not noticed this technology moved toward the mature symptom.” “……可是我听说,量子通讯技术不简单吧？咱们国家在这一块还算是走在比较前面的,成果也有不少了,但我一直都没看到这项技术走向成熟的苗头。” „Could not see that this symptom is very normal,” Lu Zhou said that „, because present this domain obtains the breakthrough main centralism to realize the photon entanglement as well as enhancement signal strength these two aspects, but wants to realize the quantum communication truly, the key lies on the quantum repeater.” “看不到这个苗头很正常,”陆舟说道,“因为现在这个领域取得突破主要集中在实现光子纠缠以及增强信号强度这两方面,但想要真正实现量子通讯,关键还是在于量子中继器上。” The segmentation words, the quantum repeater can also subdivide for „quantum memory” again downward and „quantum state reads and the optimization in efficiency and storage time of reading out” these two propositions. 再往下细分的话,量子中继器还可以细分为“量子存储器”和“量子态写入和读出的效率与存储时间上的最优化”这两个命题。 But these two big technical problems, in the dlcz plan mentioned, using quantum memory and single photon channel unifies to suppress to weaken, realizes long distance quantum communication. 而这两大技术难点,正是在dlcz方案中提到的,利用量子存储器和单光子信道的结合以抑制衰减,来实现长距离的量子通讯。 However, because quantum memory basically no significant progress, causing the quantum communication only to be able the distance in hundred kilometers to realize, moreover to transmitting the environment the request is quite harsh. But this also lost the value of practical application, even was once suspected is possible to realize. 然而,由于量子存储器这一块基本上没有什么重大进展,导致量子通讯只能够在百公里以内的距离实现,而且对传输环境的要求极为苛刻。而这也就失去了实用化的价值,甚至于一度被人怀疑到底可不可能实现。 „Quantum repeater?” “量子中继器？” „Un,” looks at Chief Li looking pensive, Lu Zhou selected, „this has anything to progress, but has not progressed completely. This point, the entire world is the same......” “嗯,”看着若有所思的李局长,陆舟点了下头,“这一块不是没什么进展,而是完全没有进展。这一点,全世界都是一样……” The quantum communication can keep secret absolutely, then because of wave function special characteristics, once gives the information the photon to be intercepted, any observation behavior will cause the avalanche of entangled state. 量子通讯之所以能够绝对保密,便是因为波函数特殊的特性,一旦传递信息的光子被截获,任何观测行为都会导致纠缠态的崩塌。 Said popular, between A and B telephone, if there is third party C to stand in the middle intercepts. What method that no matter C adopts, pastes the ear with the wiretap device on the wall, so long as were heard a character by C, A and B can know that immediately the communication was intercepted, and entire information will also lose the significance. 说的通俗一点,a和b之间打电话,如果有个第三者c站在中间窃听。不管c采取的何种手段,用窃听器还是把耳朵贴在墙上,只要被c听到了一个字,a和b马上就能知道通讯被窃听,并且整段信息也会随之失去意义。 Including the asymmetric cryptography algorithm, is the traditional communication methods that all encryption algorithms aim. But in the face of the quantum communication technology, the encryption is unnecessary. 包括非对称加密算法在内,一切加密算法针对的都是传统通讯手段。而在量子通讯技术面前,加密根本是多余的。 This is also so-called „unconditionally security”! 这也就是所谓的“无条件安全”！ Spent for probably five minutes, Lu Zhou the technical problem of quantum communication as well as it compared to the advantage of traditional communication method, to Chief Li simply speaking. 花了大概五分钟的时间,陆舟将量子通讯的技术难点以及其相对于传统通讯手段的优势,给李局长简单地讲了一遍。 Although is some platitudes things, before Chief Li, listens to many people and he has spoken similar thing, but these said time after all from the Academician Lu mouth, the instantaneous significance was different. 虽然都是些老生常谈的东西,李局长以前也听不少人和他讲过类似的东西,但这一次毕竟是从陆院士嘴里讲出来的,瞬间意义就不一样了。 After listening to the explanation of Lu Zhou, his heart fiery, pursues immediately hastily asks. 在听完了陆舟的解释之后,他的心头顿时一阵火热,连忙追问道。 „This ‚unconditionally security’ the quantum communication, is doing very difficult?” “这个‘无条件安全’的量子通讯,很搞难吗？” Lu Zhou look earnest place under. 陆舟神色认真地点了下头。 „To be honest, is not only very difficult! But quite difficult!” “说实话,不仅仅是很难！而是相当的难！” „Spoke the part that you could not understand regardless these me, you only needed to know, this gadget basically is limit quantum communication technology commercializing the bottleneck of most core on the line.” “抛开那些我讲了你也听不懂的部分,你只需要知道,这玩意儿基本上已经是限制量子通讯技术商用化的最核心的瓶颈就行了。” In the office was again peaceful. 办公室里再次安静了。 This peaceful time is a little long. 这一次安静的时间有一点长。 Lu Zhou took up the drinking glass on table to drink one, sleek/moist the mulberry, prepared to comfort this old friend two, and told him not to need extremely to worry. That wrap/sets encryption algorithm can definitely first use, when 2000 Qubit's computer comes out, said that did not permit the research of quantum repeater also to have the new progress. 陆舟拿起桌上的水杯喝了一口,润了润桑子,准备安慰这位老朋友两句,并告诉他不用太过着急。那套加密算法完全可以先用着,等到2000量子比特的计算机出来,说不准量子中继器的研究也有了新的进展。 The birth of any new technology, requires the time to precipitate, that set of quantum encryption algorithm that although he develops in he opinion is not what specially wise thing, but will have no issue on some time. 任何新技术的诞生,都是需要时间去沉淀的,虽然他开发的那套量子加密算法在他自己看来也不算什么特别高明的东西,但将就一段时间还是没什么问题的。 However when he is just about to open the mouth, Chief Li actually forestalled freely one step according , the whole face opened the mouth to ask anxiously. 然而就在他正要开口的时候,李局长却是按奈不住地抢先了一步,满脸猴急地开口问道。 „...... That, that quantum repeater, can you handle?” “……那,那个量子中继器,您能搞定吗？” Lu Zhou: „........................” 陆舟:“……………………”
