Comes out after the laboratory, Lu Zhou hints Academician Xue to wait a bit a while, later looked to two security personnel who stand in the entrance, said with the earnest tone injunction. 从实验室出来之后,陆舟示意薛院士稍等一会儿,随后看向了站在门口的两名安保人员,用认真的语气嘱咐道。 „Adjusts Class A here security rank, only if I, anybody can not approach here.” “将这里的保密级别调整到甲级,除非是我本人,任何人不得靠近这里。” Two securities stand at attention to stand firm, lifted the hand neatly good a military salute. 两名保安立正站定,干净利落地抬手行了个军礼。 „Yes.” “是。” After leaving the institute of semiconductors, Academician Xue looked that to asked in nearby Lu Zhou. 离开了半导体研究所之后,薛院士看向走在旁边的陆舟问道。 „Are the people of army?” “他们是部队的人？” Lu Zhou: „Retired career change, I and their regimental commanders relate well, the help arranged the work.” 陆舟:“退伍转业的,我和他们团长关系不错,就帮忙安排工作了。” Comes out from the army, at least the political investigation does not need him to worry, person Commander wears who the political investigation does not go through a strategic pass will not recommend to him. Moreover the person who in the security ability, comes out from the army also by far recruit the person who arrives at to be much stronger than the general way, basic training can omit continually, can go on duty directly. 从部队里出来的,至少政审不用他操心,政审不过关的人戴团长也不会推荐给他。而且在安保能力上,从部队里出来的人也远远要比一般途径招到的人强得多,连基本的培训都可以省去了,直接就能上岗。 Jinling Higher Research institute from establishing to the present, let alone is the material is the victim this kind of criminal case, has not lost including a scratch paper, lovable people who depended these adhere faithfully. 金陵高等研究院从成立到现在,别说是材料失窃这类刑事案件,连一张草稿纸都没有丢过,靠的正是这些恪尽职守的可爱的人们。 Led Academician Xue to come to the office, Lu Zhou told that the secretary gave him to pour cup of tea, and helped itself but actually. the coffee cup 带着薛院士来到了办公室,陆舟吩咐秘书给他倒了杯茶,并且帮自己倒了杯咖啡。 After completing these things, that secretary left the office very much tactful, and took the gate conveniently. 做完了这些事情之后,那位秘书很识趣地离开了办公室,并且顺手带上了门。 Looks at the gate to close, Lu Zhou continues to look that to sat in his opposite venerable, smiles to say. 看着门关上,陆舟继续看向了坐在他对面的老先生,笑了笑开口说道。 „I guess that you have the lots to ask, you first invited.” “我猜你有很多东西想问,你先请吧。” Academician Xue silent a while, sighed to say gently. 薛院士沉默了一会儿,轻轻叹了口气说道。 „Before here, I really has many confusion, but...... I feel that now I get the answer. Let alone......” “在来这里之前,我确实有许多的困惑,但现在……我感觉我已经得到答案了。何况……” The smiling face of senior academician took some light mixed feelings. 老院士的笑容带上了些许淡淡的复杂的感觉。 „...... The cryptology, has been able to leave the stage of history.” “……密码学,已经可以退出历史的舞台了吧。” Lu Zhou shakes the head. 陆舟摇了摇头。 „This view was too absolute, the renewal of any technology requires the time, like even if had the fusion power like this to be clean and efficient energy, the coal electricity still grabbed the market share of this small part in our big western area......” “这个说法太绝对了,任何技术的更新换代都需要时间,就像哪怕是拥有了聚变能这样清洁而高效的能源,煤电在我们的大西部地区仍然占据这一小部分的市场份额……” „Let alone, those who leave the historical arena is only utilization of the encryption algorithm in long distance communication, from the base depot to individual short distance communication, as well as other domains, the cryptology can still play a big role......” “何况,退出历史舞台的只是加密算法在长距离通讯中的运用,在从基站到个人的短距离通讯上,以及其他领域,密码学仍然能发挥不小的作用……” , Lu Zhou looks Academician Xue continues to say. 顿了顿,陆舟看着薛院士继续说道。 „...... Needs, makes some adjustments merely.” “……而需要的,仅仅是做出一些调整。” Is chewing Lu Zhou these words repeatedly, Academician Xue is lost in thought. 反复嘴嚼着陆舟这句话,薛院士陷入了沉思。 Has not disturbed his ponder, Lu Zhou to carry the coffee cup, blows that curling white fog, slowly drank one. 没有打扰他的思考,陆舟端起咖啡杯,吹了吹那袅袅白雾,慢慢地喝了一口。 Crossed for five minutes is so long probably, Academician Xue lifted finally, said earnestly. 大概过了五分钟那么久,薛院士终于抬起了头来,认真说道。 „Has the place that what I can help?” “有什么我可以帮上忙的地方吗？” On the face of Lu Zhou showed the smiling face of applause. 陆舟的脸上露出了赞许的笑容。 „Naturally.” “当然。” „I have several issues, expert who needs to consult the relevant area.” “我有几个问题,需要咨询相关领域的专家。” Academician Xue: „Which aspect?” 薛院士:“哪方面？” „About quantum communication.” “关于量子通讯。” Hears these words, Academician Xue gawked slightly , the expression somewhat said slightly embarrassed: „Quantum communication this...... I am not this expert in aspect, you should look for the professor of University of Science and Technology of China......” 听到这句话,薛院士微微愣了下,表情略微有些窘迫地说道:“量子通信这个……我不是这方面的专家,你应该找科大的教授……” „Before you come to here, I have sent the professor ditch of mail and University of Science and Technology of China passed, but after hearing my issue, they to you who I recommend.” “早在你来这里之前,我就已经发去邮件和科大的教授沟通过了,而在听到了我的问题之后,他们向我推荐的正是您。” Looks at Academician Xue, Lu Zhou continues saying that „besides the cryptology, you is also a telecommunications project domain expert, once was the senior engineer in Chinese electron 46, and has participated in the construction of domestic early optical network.” 看着薛院士,陆舟继续说道,“除了密码学之外,您本身也是一名通信工程领域的专家,曾经在中国电子46所担任高级工程师,并且参与过国内早期光纤网络的建设。” Hears these to make the matter that one fondly remembers, Academician Xue in the eye floated off several recollections. 听到这些令人怀念的事情,薛院士眼中浮起了几丝回忆。 However finally, he shakes the head. 不过最终,他还是摇了摇头。 „That was some aging past events, I basically changed over to since 10 years to the communications security direction, perhaps was very difficult to add on your busy.” “那都是些陈年往事了,我从十年开始基本上就转入到通信安全方向了,恐怕很难帮上你的忙。” „But I believe that experiences this type of thing is not obsolete,” Lu Zhou said earnestly, „particularly when we need to build this communications network.” “但我相信经验这种东西是不会过时的,”陆舟认真说道,“尤其是在我们需要重新建立这个通讯网络的时候。” Is hearing these words the instance, Academician Xue the heart shakes, cannot believe that looks at Lu Zhou. 在听到这句话的瞬间,薛院士心头一震,不敢相信地看着陆舟。 „Your meaning is, you planned that...... you do plan to use that type...... the quantum optical fiber? Builds the domestic communications network?” “你的意思是,你打算……你打算用那种……量子光纤？重新搭建国内的通讯网络？” „This arrives is not my plan.” “这到不是我的打算。” Looks Academician Xue who the sound has started to speak incoherently, Lu Zhou smiles lightly , to continue to say with the tone of cracking a joke. 看着声音已经开始语无伦次的薛院士,陆舟淡淡笑了笑,用开玩笑的语气继续说道。 „Moreover, I had not said is only the home.” “而且,我可没说过只是国内。” ...... …… Once the issue of quantum repeater is solved, the entire quantum communication technology has the possibility of commercializing. 量子中继器的问题一旦解决,整个量子通讯技术已经具备了商用化的可能。 However the quantum communication technology has a very fatal shortcoming, in data quantity that then in unit of time transmits. 然而量子通讯技术有个很致命的缺点,那便是在单位时间内传输的数据量上。 Takes from west coast of US to China east coast undersea lightwave cable for instance, its band width frequently takes tbps as the unit. 以从美国西海岸到华国东海岸的海底光缆为例,其带宽动辄以tbps为单位。 The data of this scale regarding the traditional optical fiber is not a difficult matter, however regarding depending upon the single photon entanglement to realizes the quantum communication technology of information transmission, this is actually the issue that in a short-term is unable to solve. 这个规模的数据对于传统光纤来说并不是一件难事,然而对于依靠单光子纠缠对来实现信息传递的量子通讯技术而言,这却是一个短期内无法解决的问题。 Simply speaking, quantum communication technology -based the communication channel, satisfies data exchanges between limited several enterprises is nothing issue, but is unable the communication of carrying/sustaining Internet this scale. 简单来说,基于量子通讯技术的通讯信道,满足有限几个企业之间的数据交换是没什么问题的,但根本无法承载互联网这种规模的通讯。 However, this also has solution. 不过,这也并非没有解决的办法。 According to the report of istfp5, 1 128 bit key can safeguard the 100 gbit data the security. Theoretically only needs a band width to achieve the mtps magnitude quantum communication channel, then gives to span all information in addition of Pacific Ocean to cage sufficiently. 按照istfp5的报告,一个128bit的密钥可以保障100gbit数据的安全。理论上只需要一条带宽达到mtps量级的量子通讯信道,便足以给跨越太平洋的所有信息加上一把锁。 Therefore, a perfect plan is, unifies the traditional communication method and quantum communication technology, with traditional communication channel transmission „locking” the information, again with the quantum communication channel distributes „unblanking” the key. 因此,一个完美的方案便是,将传统通讯手段和量子通讯技术结合起来,用传统通讯信道发送“加锁”的信息,再用量子通讯信道分发“开锁”的密钥。 Abstract description, is the big hand delivers the package, slightly hands over the key. 抽象的形容,就是大手送包裹,小手递钥匙。 This being approximate in „one-time padding” the encryption method, can achieve „unconditionally security” theoretically degree. Key unique that if unlocks, then quick computer, impossible to steal the key through the pure operation strength. 这种近似于“一次一密”的加密方式,理论上也能够达到“无条件安全”的程度。如果开锁的钥匙只有独一无二的一把,那么无论是多快的计算机,也不可能通过单纯的运算力窃取密钥。 In order to realize the key and by encryption information the separation, was needed one set of brand-new communications protocol to realize. Not only so, to raise the information transport efficiency, is used to assign the quantum communication network of key, must undergo the rigorous design. 为了实现密钥和被加密信息的分离,需要一套全新的通讯协议来实现。不只是如此,为了提高信息的传输效率,用来分配密钥的量子通信网络,必须经过严谨的设计。 Must acknowledge, this is not an easy work. 必须得承认,这不是一件容易的工作。 But how regardless to say, compares the quantum repeater, was easy is too many. 但无论怎么说,相比起量子中继器而言,还是容易太多了。 Almost nothing hesitant, Academician Xue then received the invitation of Lu Zhou at the scene, participated in the project of construction quantum communication network, to visit the name of exchange to stay in Jinling University. 几乎没有任何犹豫,薛院士当场便接下了陆舟的邀请,参与到了建设量子通信网络的项目,以访问交流的名义留在了金陵大学这边。 Happen, how he is still worrying avoids these to wait for him go to the Ministry of Industry that side „to ask for an explanation” the colleagues and old friends. 正好,他还在发愁如何躲开那些等着他去工信部那边“讨个说法”的同事和老朋友们。 Although the manages was quiet is very easy, but did to the industry circle that he was engaged in is really small. 虽说管住嘴很容易,但奈何他所从事的这个行业圈子实在是太小了。 Even if the lots his anything did not say, look others also anything guessed correctly. 很多东西哪怕他什么也不说,一个眼神别人也什么都猜到了。 No matter is also good for the general situation, is for he himself, leaving some time is the best choice...... 不管是为了大局也好,还是为了他自己,离开一段时间都是最好的选择…… With joining of Academician Xue, the project of entire quantum communication network, the speed of advancement can think to come at once to describe. Relied on the experience of this venerable, Lu Zhou was soon finding the quantum communication technology and method of optimization of traditional mechanics of communication integration, and completed a constitutive frame to this brand-new communications protocol. 随着薛院士的加入,整个量子通讯网络的项目,推进的速度可以用神速来形容。凭借着这位老先生的经验,陆舟很快找到了量子通讯技术与传统通讯技术结合的最优化方法,并对这个崭新的通讯协议完成了一个结构性的框架。 Then, the time passes day-by-day, finally to April last day. 就这样,时间一天天过去,终于到了四月的最后一天。 A length approximately 500 meters experimental quantum communication pipeline, an corner/horn that conceals in Jinling Higher Research institute completes. But at the same time, this ivory tower that stands erect in the China academic circle peak, welcomed a status special guest...... 一条长度约五百米的实验用量子通讯管道,在金陵高等研究院隐瞒的一角建成。而与此同时,这座屹立在华国学术界顶端的象牙塔,也迎来了一位身份特殊的客人…… Lamp pen 灯笔
