Perhaps is knows that own request is somewhat embarrassing, Chief Li these words just said that sound unconscious then getting smaller. 或许是知道自己的请求有些让人为难,李局长这句话刚说出口,声音不自觉的便越来越小。 However adjusts the small volume unable to let this request that feels embarrassed the person sounds more tactful, therefore he suffered a Lu Zhou supercilious look finally. 然而调小音量并不能让这句为难人的请求听起来更加委婉,因此他最终还是挨了陆舟一记白眼。 „Which my words were tell you to solve the problem the key, did not make you continue to ask how I solved the problem!” “我刚才的那番话是告诉你解决问题的关键在哪,不是让你来继续问我怎么解决问题的！” However, facing Lu Zhou tsukomi, Chief Li, not only no meaning of introspection, instead is continues to say brazenly. 然而,面对陆舟的吐槽,李局长非但没有任何反省的意思,反而是厚着脸皮继续说道。 „This...... the issue you found in any case, solved it simply was not good?” “这个……反正问题你都找到了,干脆把它解决了不行吗？” Looks on Li Ju long face that embarrassed smiling face, Lu Zhou will have an misconception. 看着李局长脸上那不好意思的笑容,陆舟不禁会产生一种错觉。 This fellow oneself regarding slightly dingdong. 这家伙是不是把自己给当成小叮当了。 It is not right, being possible is not the misconception. 不对,有可能不是错觉。 80% are like this...... 八成就是这样子的…… ...... …… „Had free time I to ponder over” with one sends Chief Li finally, saw the time similarly also Lu Zhou, telephones to Wang Peng, then went to the parking lot directly. 用一句“有空我会琢磨琢磨”总算是打发走了李局长,见时间也差不多了的陆舟,给王鹏打了个电话,然后便径直前往了停车场。 Rode on a black sedan, looks that Wang Peng took the steering wheel to open the road the taxi, sat says in back row Lu Zhou suddenly. 坐到了一辆黑色的轿车上,看着王鹏打着方向盘将车开上了公路,坐在后排的陆舟忽然开口说道。 „Wang Peng.” “王鹏。” „What matter?” “什么事？” Lu Zhou thinks to say. 陆舟想了想开口说。 „In your opinion, what is the science?” “在你看来,科学是什么？” Regarding Lu Zhou will ask occasionally some own strange issues, Wang Peng was also becomes accustomed. 对于陆舟偶尔会问自己一些奇怪的问题,王鹏也算是习以为常了。 Seriously pondered a while, he says. 认真思考了一会儿,他开口说道。 „I felt, should be the way of solving the problem, is similar to” “我觉得,应该是解决问题的途径,大概就类似于” „Similar to letting the water burns, lets the air setting, lets the steel flight...... is this meaning?” “类似于让水燃烧,让空气凝固,让钢铁飞行……是这个意思吗？” Wang Peng thinks, although thought that this view is a little abstract, but feels like also no problem, therefore selected under. 王鹏想了想,虽然觉得这个说法有点抽象,但觉得好像也没啥毛病,于是点了下头。 „Almost.” “差不多吧。” Hears this expected answer, Lu Zhou sighs gently. 听到这个意料之中的答案,陆舟轻轻叹了口气。 „Therefore , this is to the science biggest misunderstanding.” “所以说,这是对科学最大的误解。” Wang Peng: „......?” 王鹏:“……？” Lu Zhou: „Goes to Jinling Higher Research institute.” 陆舟:“去金陵高等研究院吧。” Wang Peng looked in a car(riage) the mirror to ask. 王鹏看了眼车内镜问道。 „Are three o'clock's conferences unimportant?” “三点钟的会议不要紧吗？” „A while I studying Chen Yushan telephone,” Lu Zhou thinks saying that „she goes is also the same.” “一会儿我会给学陈玉珊打个电话,”陆舟想了想说道,“她去也是一样的。” ...... …… As a result of the quantum communication the interaction of system and channel, will cause in the system the coherence of pure state to weaken, thus causes to superimpose ingredient the randomness of internal phase difference to increase respectively, causes the quantum information bust this. 由于量子通信系统与信道的相互作用,会引起系统中纯态的相干性衰减,从而使各叠加成分的内部相位差的随机性增加,导致量子信息传输失败。 Quite friendly solution is, to traditional communication method such, separates a distance to increase a repeater, the signal amplification that will weaken continues to transmit. 比较友善的解决方法就是,向传统通讯手段那样,隔一段距离增加一个中继器,将衰减的信号放大继续发送。 However this method sounds like very easy, but regarding the quantum communication method, actually difficult such as to ascend to heaven. What because the quantum communication mainly bases on is the single photon spin state quantum effect completes, but the enlargement optical device can destroy the quantum bit. 然而这种方法听起来似乎很容易,但对于量子通讯手段来说,却难如登天。因为量子通讯主要基于的是单光子自旋态的量子效应来完成的,而放大光学器件会破坏量子位元。 At present relays the technology to be divided into two types, one type is credible relaying, one type is the quantum repeater. 目前中继技术分为两种,一种是可信中继,还有一种是量子中继。 The former is similar to the key relay, making the key transmit in the workstations that can trust. Relatively latter, the technical difficulty is slightly low, but the issue lies in once the relay station were controlled by the hostile forces, has the possibility of interception. 前者类似于密钥接力,让密钥在可以信任的工作站之间传递。相对后者而言,技术难度稍微低一点,但问题就在于一旦中继站被敌对势力控制,就存在窃听的可能。 In other words, with the words of this technological line, establishes unconditionally safely, in „workstation is credible” at premise. 换句话说,采用这条技术路线的话,无条件安全就是建立在“工作站可信”的前提上的。 But latter, then bases on the entanglement distribution technology, establishes sharing to pester right in the neighboring sites, will pester by the quantum storage technology to storing up, and realizes the sharing entanglement using the entanglement swapping operation in the neighboring sites. 而后者,则是基于量子纠缠分发技术,在相邻站点之间建立共享纠缠对,以量子存储技术将纠缠对储存,并应用纠缠转换操作在邻近站点之间实现共享纠缠。 In the security, the latter naturally is unequalled, but the price is the technical difficulty is quite big, to that does not have the friend, around 07 years the academic circle once gave up. 在安全性上,后者自然是无与伦比,但代价就是技术难度相当大,大到了没朋友的那种,07年前后学术界一度放弃。 Objective, if only the communication in national territory, for example takes the defense special line, is completely then enough with credible relaying. Like „the Beijing-Shanghai skeleton lines” and Mozi such, under the protection of people's army, is impossible had to say the workstation by „seizure” the condition. 客观的来讲,如果只是国土内的通讯的话,比如作为军工专线,采用可信中继便完全足够。就像“京沪干线”和墨子号那样,在人民军队的保护下,不可能存在说工作站被“占领”的状况。 When the message area expands to the global scale, the security of overseas site is unable to obtain 100% credible guarantees, the security of credible relaying canned be discussed. 然而当通讯范围扩大到全球范围,境外站点的安全性无法得到百分之百的可信保证,可信中继的安全性就有待商榷了。 In information globalization immediately, any country is impossible to be separated from Internet this big collective, Chief Li expects obviously is not the technology that type can only close oneself to play. 在信息全球化的当下,任何国家都不可能脱离互联网这个大集体,李局长期望的显然也不是那种只能关上门自己玩的技术。 Therefore, the key of issue is, how to solve the bottleneck of quantum repeater. 因此,问题的关键就在于,如何解决掉量子中继器的瓶颈了。 Arrived at Jinling Higher Research institute, Lu Zhou and Chen Yushan telephones, afternoon conference will entrust to her processed, and edited a mail, sent to the conference program her mailbox. 来到了金陵高等研究院,陆舟和陈玉珊打了个电话,将下午的会议委托给了她去处理,并且编辑了一封邮件,将会议大纲发到了她的邮箱中。 Conference main discussion is the working arrangement of lunar surface quality accelerator project, in him already beforehand working arrangement in the situation, may not he personally act to be good. 会议主要讨论的便是月面质量加速器项目的工作安排,在他已经事先将工作安排好了的情况下,不一定非得他亲自出面才行。 In comparison, a more important matter waits for him to be done. 相比之下,还有更重要的事情等着他去做。 Arrived at the underground research institute, Lu Zhou arrived studied the carbon base quantum processor chip in a while ago that laboratory, looks at the carbon base integrated circuit board of seal in transparent vessel, thought aloud that said. 来到了地下研究所,陆舟走到了前段时间研究碳基量子处理器芯片的那间实验室里,看着封装在透明容器内的碳基集成电路板,自言自语地说道。 „Originally planned to handle the cislunar control project to study this topic again.” “本来打算搞定了地月掌控项目再来研究这个课题的。” „, First tried to say in brief again.” “也罢,总之先试试再说吧。” Saying, Lu Zhou hinted Xiao Ai to find time the inert gas in transparent vessel, and relieved the combination lock, put on the special glove to take from inside that well-preserved carbon base integrated circuit board. 说着,陆舟示意小艾抽空了透明容器内的惰性气体,并解除了密码锁,戴上特殊的手套将那个保存完好的碳基集成电路板从里面取了出来。 The difficulty of quantum repeater can be divided into three parts, the entanglement swapping, the entanglement purification, as well as quantum memory. 量子中继器的难点可以分为三个部分,纠缠交换,纠缠纯化,以及量子存储。 First two said fortunately, as for last, basically is at the difficult problem of same dimension with the quantum computer. 前两个都还好说,至于最后一个,基本上和量子计算机是处在同一个维度的难题。 However what is interesting, the research of quantum memory and quantum computer to a certain extent, has the superposition the place. The difference merely is, the quantum memory is almost essential regarding the quantum communication of long distance, but actually just did not need regarding the quantum computer. 不过有意思的是,量子存储器和量子计算机的研究在某种程度上,存在重合的地方。区别仅仅是在于,量子存储器对于长距离的量子通讯来说几乎是必不可少的,但对于量子计算机而言却并非是刚需。 Some words, can produce more advanced quantum computer, if no, there is a not that advanced quantum computer to choose...... is also that his diy comes out. 有的话,可以造更先进的量子计算机,没有的话,也有不那么先进的量子计算机可以选择……也就是他自己diy出来的那个。 In fact, Lu Zhou temporarily. When has not studied quantum memory technology, over 80% reasons are also for this factor. 事实上,陆舟之所以暂.时没有研究量子存储器这一块的技术,八成以上的原因也正是出于这一层因素的考虑。 In his original idea, with quantum computer technological breakthrough, and widely was applied in the commercial sector, the capital will promote the quantum memory technology to forge ahead naturally, to seek the construction speed to be quicker, the handling capacity stronger quantum computer. 在他原本的想法中,随着量子计算机技术突破,并且被广泛地应用于商业领域,资本自然而然会推动量子存储器技术向前迈进,以寻求建造速度更快、处理能力更强的量子计算机。 When the time comes does not need him to make the too big effort, does not need to waste precious General points, naturally can obtain him to expect the quantum memory technology. 到时候根本不用他花太大的力气,也根本不需要浪费宝贵的积分,自然而然的就能得到他期望中的量子存储器技术。 „System of memory in memory cannot maintain in the entire storage time in any remote systems the entanglement between in memory......” “存储在存储器中的系统与不在存储器中的任何远程系统之间的量子纠缠必须在整个存储时间内保持……” „If this entanglement were destroyed at any time, for example because of observing to have collapsing, then this/should equipment is not then able to begin to the function of quantum memory, but the exuviate turn into ‚entanglement interrupt channel’, can only transmit the classical information.” “如果这种纠缠在任何时候被破坏,比如因为观测而发生坍塌,那么该设备便无法再起到量子存储器的作用,而是蜕变成‘纠缠中断信道’,只能传输经典信息。” „Is a little difficult to do......” “有点难搞啊……” Looked at carefully is lying down that integrated circuit board on test installation, Lu Zhou ponders was very long. 端详着躺在实验设备上的那块集成电路板,陆舟沉思了很久。 Passed through a big standard to the minute hand, he thinks suddenly anything resembles, says. 一直到分针走过了一大格,他才忽然想到了什么似的,开口说道。 „This is not the topic that a person can complete.” “这不是一个人能够完成的课题。” „......” “不过……” „I quite think that is not an average person.” “我好想不是一般人。” Xiao Ai: 【(??????)】 小艾:【(？?????)】 Thought aloud that is whispering, sits Lu Zhou before experiment table, suddenly took the ball pen, wrote down one line of characters on the scratch paper. 自言自语地嘀咕着,坐在实验桌前的陆舟,忽然拿起了圆珠笔,在草稿纸上写下了一行字。 【Three dimensional quantum memory】 【三维量子记忆体】 Looks on the paper these seven neat large characters, Lu Zhou nods satisfied. 看着纸上这七个工整的大字,陆舟满意地点了点头。 „Temporarily first called this name to be good!” “暂时先叫这个名字好了！”
