4. 薛定谔为什么翻译作薛定谔
晕是薛定谔的猫
薛定谔的猫
物理学 周飞 王玲丽
猫的诞生
薛定谔对量子力学的"哥本哈根解释"经常提出质疑. 1935 年.薛定谔对量子力学哥本哈根学派提出了又一次挑战.他设想一种理想实验:
"一只猫关在一个钢盒内,盒中有下述极残忍的装置(必须保证此装置不受猫的直接干扰):在盖革计数器中有一小块辐射物质,它非常小,或许在1 小时内只有一个原子衰变.在相同的几率下或许没有一个原子衰变.如果发生衰变,计数管便放电,并通过继电器释放一锤,击碎 一个小的氢氰酸瓶.如果人们使这整个系统自己存在1 个小时, 那么人们会说,如果在期间没有原子衰变,这猫就是活的.而第一次原子衰变必定会毒杀了猫."
猫的照片
我们心中的猫
根据量子力学,盒内整个系统处于两种态的叠加
之中,其中第一分量意味着死猫与原子嬗变态|e>的关联;第二分量意味着活猫与原子稳态|g>的关联.这样的关联状态就是所谓的量子纠缠态.
我们看猫
那么,在这个箱子里的猫究竟是死的还是活的呢 按照以玻尔为代表的哥本哈根学派的解释,放射性原子的衰变可以用波函数来描述.在没有打开箱子时,放射性原子进入了衰变与不衰变的迭加态,这时猫就成了一只处于迭加态的猫,即一只又死又活,半死半活的猫.只有当实验者打开箱子的时候,波函数突然"坍缩",我们才能知道猫的确定态:死,或者活.
然而,猫却不这样认为
是死是活,
我心里明白
理论上讲, 猫自己还是知道自己是活还是死的.
但根据量子测量假说,处在这种怪态上,猫的生死是打开盒子前的"客观存在",但又决定于打开盒子后的"观察".看上去这个推论是不合理的,因而称之为"薛定谔猫佯谬".
如果盒子还有一个人,猫的生死他是知道的,他是否会得到与盒外观察者一样的结果呢
多宇宙解释
当你掷骰子,它看起会随机得到一个特定的结果.然而量子力学指出,那一瞬间你实际上掷出了每一个状态,骰子在不同的宇宙
中停在不同的点数.其中一个宇宙里,你掷出了1,另一个宇宙里你掷出了2…….然而我们仅能看到全部真实的一小部分--其中一个宇宙.
多宇宙解释中的猫
多宇宙认为猫并未叠加,而是"分裂"成了两只,一死一活,必定有一只活猫!只不过它们存在于两个平行的世界中.
多宇宙理论中的问题——量子永生
现在假如有一位勇于为科学献身的仁人义士,他自告奋勇地去代替那只倒霉的猫.根据多宇宙,必定有一个你看到瓶子碎掉,另一个你在另一个世界里看到瓶子仍然完整.但问题是,看到瓶碎的那位随即就死掉了,什么感觉都没有了,这个世界对"你"来说就已经没有意义了.对你来说,唯一有意义的世界就是你活着的那个世界.
所以,从人择原理的角度上来讲,对你唯一有意义的"存在"就是那些你活着的世界.你永远只会看到瓶子完好无损而继续活着!因为多宇宙和哥本哈根不同,永远都会有一个你活在某个世界!
如果多宇宙理论是正确的,那么我们得到的推论是:一旦一个"意识"开始存在,从它自身的角度来看,它就必定永生!
寻找新的解释
既然量子论是正确的,那么叠加性必然是一种普遍现象.可是,为什么火星有着一条确定的轨道,而不是从轨道上向外散开去呢
自然,答案在哥本哈根派的锦囊中是唾手可得:火星之所以不散开去,是因为有人在"观察"它,或者说有人在看着它.每看一次,它的波函数就坍缩了.但无论费米还是盖尔曼,都觉得这个答案太无聊和愚蠢,必定有一种更好的解释.
新的解释——量子退相干
现在除非存在某种机制,破坏猫的内部状态或死猫和活猫(波包内部或波包之间)的相干叠加,"薛定谔猫佯谬"和宏观物体空间局域化问题在逻辑和常识上才能得到自恰的解决.
目前,可以用量子纠缠诱导量子退相干的观点,对薛定谔猫徉谬和宏观物体的空间定域化问题给出可能的物理解答.
量子退相干
定性地说,一方面,组成宏观物体的内部微观粒子的个体无规运动,以及宏观物体所处的环境的随机运动,会与宏观物体的集体自由度耦合纠缠起来,产生对集体自由度的广义量子测量.随着环境的自由度或组成宏观物体的粒子数增多,与之相互作用的量子系统会出现量子退相干,使得量子相干叠加名存实亡.由此看来,"薛定谔猫佯谬"和宏观物体的空间定域化问题有可能起因于对问题的不恰当地表述.
量子退相干
量子测量会引起量子退相干
现在可以设想,环境的作用和宏观物体的内部的影响,相当于对集体自由度进行有效的量子测量,形成环境的或宏观物体的内部与系统间的纠缠态.从这一角度,Wigner 及 Joos 和 Zeh 讨论了解决薛定谔猫徉谬和宏观物体的空间定域化问题的可能性:环境粒子与宏观物体散射会形成宏观物体和散射粒子(真空光子,空气的原子分子)之间的量子纠缠态,从而环境粒子能够记录宏观物体的"which-way"信息.特别是,依据Omnes "内部环境"的观念,我们因子化理论的分析不限于环境诱导量子退相干,可以包括组成宏观物体的微观粒子的个体无规运动引起量子退相干的分析.这就强调了,即使把宏观物体与其环境完全隔离开,量子退相干也会发生.
用退相干理论去理解猫
谈到的宏观物体-"猫"的"死"和"活"是代表猫两种集体状态(或两个宏观可区别的波包),如质心自由度所处的状态.由于宏观物体由大量微观粒子组成,其组成的部分的运动不是严格地协调一致.在这种情况下,必须考虑众多内部自由度对集体态的影响. 这种影响与集体状态形成理想的量子纠缠,"平均掉"内部自由度的影响,宏观物体的相干叠加性就会被破坏了:死猫与原子嬗变态|e>的关联和活猫与原子稳态|g>的关联是经典的.
猫儿的处境快清楚了
这是一个客观的概率性事件,并不依赖人们去观察什么.这与量子纠缠态 描述的概率性事件有本质的不同,因为后者依赖于人们去观察什么.(可以观测 |e> 或 |g>,也可以观测|e> 和 |g> 的相干叠加,二者会给出不同的关联).因此,虽然形式地写出了死态与活态的相干叠加,但在严格的意义下,只要谈到通常的"宏观物体",其相干性是不存在的.
猫的"死"和"活"是不相干的
由于薛定谔猫是一个宏观物体,它具有非常大的状态空间和特别密集的能谱.例如,我们假设"猫"是由N 个二能级原子组成;每个粒子的基态能量为0,而激发态的能量为 E,则猫的总能量必处于0 和 NE 之间,而可能存在的不同状态总数为2N,则平均能量间隔为NE/2N .因此,当N 很大时,能量间隔趋近于零.由于能级间隔很小,内部状态既便经历了一个很小的扰动,也很容易跃迁到不同的状态上.就是说,集体自由度在不同的状态上会对不同的内部状态产生不同的影响.上述不稳定性会导致与"死"和"活"关联的内部状态不一样.事实上,由于内态包含了很多分量,只要其中一个正交,便出现了量子退相干.
实验中的"薛定谔猫"
以上的讨论只是表明在通常的情况下,由于各种量子退相干的原因,象"猫"这样的宏观物体不会稳定地处于一个相干叠加态上.但是,在极特殊的情况下宏观量子态还是可能存在的.这种情况有二:
如果组成宏观物体的内部分量能"协调一致",存在 某种相位匹配,则有可能形成宏观量子态.这方面一个典型的例子是超导和玻色-爱因斯坦凝聚(BEC).
如果组成宏观物体的内部分量相对固定,宏观物体的内部自由度不被与集体自由度的耦合所激发.Zeilinger 研究小组C60 分子的量子干涉实验便属于这种情况.
结束语
"薛定谔猫"是被作为质疑量子力学的极端例子提出来的,但围绕着它一系列量子力学基本问题的研究,其寓意是十分深刻的.一方面,薛定谔猫为我们提供了从量子力学过渡到经典力学的范例,使人们充分领略到退相干过程的基本物理含义,并寻求比量子力学更基本的底层理论;另一方面,由于人们能够在特殊的条件下,制备出各种各样薛定谔猫态,使得量子力学适用的领域,从微观直接延伸到宏观,其进一步应用有可能发现新的,更宜于实际实现的量子信息载体.

Juan sic. 3.3 VRML技术VRML是虚拟实境描述模型语言(Virtual Reality Modeling Language) 的简称。 3.3 VRML technology is VRML Virtual Reality Modeling Language (Virtual Reality Modeling Language) the short title. 它是描述虚拟环境中场景的一种标准,也是在网上实现虚拟现实的关键性技术。 It is described in a virtual environment of a standard scene, but also the Internet to achieve the key technologies of virtual reality. VRML的基本特征包括分布式、交互式、平台无关、三维、多媒体集成、逼真自然等,被成为“第二代WEB”,已经被越来越多的人们所重视。 The basic feature of VRML, including distributed, interactive, platform-independent, three-dimensional, multi-media integration, life-like nature, was a "second-generation WEB", has been more and more people paying attention to. 国际标准化组织1998年1月正式将其批准为国际标准。 International Organization for Standardization in January 1998 officially approved as international standards. VRML是一种建模语言,其基本目标是建立Internet上的交互式三维多媒体,也就是说,它是用来描述三维物体及其行为的,可以构建虚拟境界。 VRML is a modeling language, its basic goal is to establish a three-dimensional Internet, interactive multimedia, in other words, it is used to describe the three-dimensional objects and their behavior, you can build a virtual realm. 用VRML实现与Internet虚拟现实交互有下面几个好处:丰富了媒体表现形式、协同工作角色的可视化管理、改善了协同环境的用户界面、增强了协同环境的交互性。 With the Internet using VRML interactive virtual reality has the following advantages: rich media manifestations, the role of the visual work of management, to improve the collaborative environment of the user interface, enhanced interactive collaborative environment. 可见,将VRML融合到网上虚拟实验室的开发过程中,既可以增强表现力和用户的接受力,又可以实现较好的协同工作虚拟化环境。 Can be seen that the VRML into the development of online virtual laboratory process, can enhance performance and user acceptance, but also work together to achieve a better virtual environment. 3.4 ASP技术ASP(Active Server Pages,动态服务器端网页),内含在Internet Information Server 3.0及其以上版本中,提供一个服务器端的脚本环境,用于产生和执行动态、高效率的网络服务器应用程序。 3.4 ASP technology ASP (Active Server Pages, Dynamic server-side page), including in the Internet Information Server 3.0 and above versions, to provide a server-side scripting environment for the generation and implementation of dynamic and efficient web server applications.

ASP提供五个内建的对象供使用者调用,即Re?鄄quest对象(取得用户信息)、Response对象(传送信息给用户)、Server对象(提供访问服务器的方法、属性)、Application对象(用于多个使用者在多个网页间共享信息)和Session对象(用于单个使用者在多个网页间共享信息)。 ASP provides a total of five built-in objects for users to call, that is, Re? Juan quest object (to obtain user information), Response object (to send information to the user), Server object (the server to provide access methods, properties), Application object (with in a variety of users to share information between multiple pages) and the Session object (for indivial users to share information between multiple pages). 4 网络虚拟实验室开发过程当中应注意的几个问题计算机软件技术发展到今天,为虚拟实验室开发提供了极大的方便。 4 virtual laboratory network development process should pay attention to several issues of the development of computer software technology to today, for the development of virtual laboratory provides great convenience. 目前开发所需的系统软件或工具均支持面向对象的程序设计。 At present, the development of the necessary system software or tools to support object-oriented programming. 它们都有事件驱动的支持,消息循环的程序设计方法及多媒体操作技术。 They have the support of event-driven news cycle of programming and multimedia skills. 在开发过程当中要注意以下几个问题:事件触发时机的选择,实际操作当中某个按钮按下后并不立即反映,需要延时回应,外部接口的输入信号或其它信息往往是定时触发或随机触发的事件,若为随机触发的事件则可用一定时限内的随机数来取代固定时间。 In the development process should pay attention to the following questions: Event trigger timing, the actual operation of them after a button press does not immediately reflect the need to delay response to the external interface of the input signal or other information from time to time is often triggered or random trigger events, if the random trigger events are available for a certain period of time the random number to replace the fixed time. 事件联锁关系或动态顺序关系可以存放在一张数据库表中描述,修改方便。 Interlocking relationship between events or dynamic order can be stored in a database table is described, modify convenience. 给定相应的条件、控制范围,自动形成数据表,使数据和程序独立。 Given the appropriate conditions, control, data tables automatically, so that an independent data and programs. 模拟声音,要使实验达到逼真,除了模拟控制台实物景象,还要模拟它们实验环境中的各种声音,如汽笛声、按钮按动声、内部机械动作声等。 Analog voice, to achieve the realistic experiment, in addition to the physical simulation of the console scene, but also simulation of their experimental sounds in the environment, such as the whistle sound, the sound button pressed, the internal mechanical action, such as sound. 这样,才能使学生在实验室有身临其境的感觉,全身心地投入学习。 In this way can help students in the laboratory are immersive feeling, to fully participate in the study. 模拟台面各种动作的结果,台面上每个控件的动作都会触发一定的事件。 Simulation results of the table a variety of movements, control the movements of each table will trigger a certain event. 这些事件在实物设备中是靠机械、电子电路等去完成,而现在将这些机械及电子逻辑关系使用计算机软件实现。 These events in the physical devices by mechanical, electronic circuits, such as to complete, and now to the relationship between mechanical and electronic logic using computer software. 故障发生器,在实际工作中除了设备正常情况下的操作,还有各种意外情况,如某些设备故障的情况。 Fault generator, in practical work in addition to equipment operation under normal circumstances, there are a variety of unforeseen circumstances, such as the failure of some equipment. 此时,要求在虚拟系统中也能模拟手柄失灵、仪表信号不显示及自然灾害发生的情况等,即给实验增加一些难度,强化学生实际操作能力。 At this point, the request in a virtual simulation system can also handle failures, instrument signals and do not show the case of natural disasters and so on, that is, to increase the difficulty of the experiment, the actual operation to strengthen the capacity of students. 5 结束语虚拟实验技术在实验教学中具有广阔的应用、发展前景,随着虚拟实验的普及,其优越性会被越来越多的人认识。 5 Conclusion virtual experiment in teaching experiments have broad applications, development prospects, with the popularity of virtual experiments, and its advantages will be more and more people are aware of. 但要使虚拟实验技术真正得到推广应用,关键还是观念的改变,首先是教师观念的改变,除了具有创新精神和能力外,还应有一个科学的投资理念,在实验室建设和发展中,充分考虑投资效益,建设现代化的实验室。 But for the virtual experiment really promote the use of technology, the key is to change the concept, first of all, the concept of change in teachers, in addition to the spirit of innovation and capacity, there should be a scientific concept of investment, construction and development in the laboratory, the full consider the investment returns and building a modern laboratory. 其次要培养一支高素质的实验队伍,不断地进行知识更新,加强学习,重视信息的收集、加工、应用,了解掌握最新技术,促进实验教学发展。 Second, we must cultivate a high-quality experimental team, continually update their knowledge to enhance learning, importance of information collection, processing, application, understand the latest technology, and promote the development of experimental teaching. 虚拟实验的应用和发展,加快了实验室发展和实验教学改革,促进了教育观念的改变。 Application of the virtual experiment and development, to accelerate the development and experimental laboratory teaching reform, the promotion of ecation to change attitudes. 是培养创新人才的新的实验手段。 Is to train innovative talents of the new experimental tools. 虚拟实验在21世纪实验教学中必将占有重要地位,无疑会起到很大的作用。 Virtual experiment experimental teaching in the 21st century will certainly occupy an important position, will undoubtedly play a significant role.

7. 定语从句中way后面什么时候加in which
当先行词是way的时候,其后的定语从句的引导词可以有三种情况:that、in which和省略不填。这是英语语法中的一个规定。
例如:I hate the way ________ Tom talks with his parents,这个题目就有三个答案,即that、in which和省略。
但是要注意的是,有很多人会错误的选择how来引导way后面的定语从句,这是错误的。究其原因是有人会习惯性地把句子翻译成为汉语,然后根据汉语的意思来选择答案。
定语的位置
定语的位置一般有两种:用在所修饰词之前的叫前置定语,用在所修饰词之后的叫后置定语。
一般不定代词、形容词、名词、数词、量词、形容性代词、冠词等作为前置定语,而过去分词、不定式、形容词短语、介词短语、定语从句、同位语从句等一般作为后置定语。
在英语里,一般定语前置时的次序为:限定词,形容词、分词、动名词和名词性定语。但当几个形容词同时出现在名词短语之前,我们要注意其次序。
以上内容参考网络-定语
8. as与in which way的区别
as(像......一样,按照)引导方式状语从句;in which way用哪种方法(方式),朝哪个方向。
He does his job as I told him. 他按照我说的做他的工作。
= He does his job in the way (that, in which) I told him.
(In )Which way did he go just now? 他刚才朝哪个方向(哪条路)走了?
In which way did he do the experiment?他是用哪种方式(方法)做这个实验的?

三篇论文造就的未来科技
- 相对论不只是抽象的理论,还可以被用来制造微晶片。工程师从爱因斯坦的想法中,持续做出各种创新的工具。
作者╱吉布斯 ( W. Wayt Gibbs )
译者╱林世昀
ATOMIC SPIN-OFFS FOR THE 21ST CENTURY
- A new generation of technologies aims to put Einstein's theories to work in computers, hospitals—even submarines
By W. Wayt Gibbs
1905年,爱因斯坦26岁,正为了完成他探讨分子大小的博士论文而奋斗。为了维持家计,他在瑞士专利局工作,专门分析其他人的发明。或许你会想,由於日常工作的启发,爱因斯坦应该会想办法把余暇时所发展的理论,做成实际的应用。可惜,在他发表他那非凡的研究生涯中最著名的五篇论文那一年,几乎看不到他有这种倾向。不过他对物质、能量和时间所主张的新看法,终究还是启发了新型机器的发明,促进了人类的工业和医疗技术。
其实爱因斯坦也不是蔑视工程学,只是工程并非他的强项而已:他自己的发明,包括不含机械式运动零件的冰箱,以及防漏帮浦,从来没有进入量产阶段。不过没有关系,经过整个20世纪,其他人基於爱因斯坦的革命性想法,也建立了许多令人印象深刻的技术,其中最有名的想法,就是光以波包的形式传播,所有的光子总是遵守同一个速限c,而且能量和物质可以相互转换,以数学语言来表示,就是E = mc2(见36页〈天天遇见爱因斯坦〉)。
到了21世纪,工程师开始用新的方式来开发那些著名原理的用途,其中或以完全创新的电脑最值得一提。他们也在为一些爱因斯坦较不为人知的理论寻找实际应用。比如说,奈米技术专家正在制作一种装置,这个装置利用分子的随机运动,来加速DNA的分析;而分子随机运动的正确解释,就是1905年由爱因斯坦首先提出的。世界上还有许多实验室,正在创造爱因斯坦於1925年的经典思考实验中所预见的各种物质特殊状态。这些同调的极冷原子群聚,是类似雷射光的物质,可以用在可携式原子钟、航行用的超精确陀螺仪,以及描绘矿脉和油田的重力感测器上。
本文将检视三种由研究实验室中脱颖而出、最新也最令人兴奋的爱因斯坦副产品;当然更多这类的创新发明,在未来的几年到几十年间,也将源源不绝而来。虽然距离这位物理大师著手发展更好的数学工具来描述宇宙的那天,已经将近一个世纪了,聪明的发明家运用爱因斯坦的理论来制作巧妙的装置,却还方兴未艾。
In 1905 Albert Einstein was 26 and struggling to finish his doctoral dissertation on the size of molecules. To pay the bills, he worked at the Swiss patent office, analyzing the inventions of others. You would think his day job would have inspired Einstein to contemplate practical uses for the theories he was developing in his spare time. Yet he showed little inkling that year, as he published five of the most remarkable papers of his extraordinary career, that the new views of matter, energy and time he was urging would eventually inspire novel kinds of machines to advance human instry and health.
It isn't that Einstein disdained engineering. It just wasn't his strong suit: his own inventions, including a refrigerator with no mechanical moving parts and a leak-proof pump, never advanced to mass proction. No matter; over the course of the 20th century, others built an impressive range of technologies [see “Everyday Einstein,” by Philip Yam, on page 50] on Einstein's radical notions that light comes in indivial packets, that those photons always obey a universal speed limit c, and that energy and matter can be interconverted: E = mc2, in mathematical shorthand.
In the 21st century, engineers have begun to exploit those famous principles in new ways, perhaps most notably in designs for radically innovative computers. They are also finding practical applications for some of Einstein's lesser-known theories. Nanotechnologists, for example, are making devices that could speed up DNA analysis by harnessing the random motion of molecules, a phenomenon first correctly explained by Einstein in 1905. And laboratories around the world are creating exotic forms of matter that Einstein envisioned in 1925 in one of his classic “thought experiments.” These coherent swarms of ultracold atoms—the matter cousins to laser beams—could find use in portable atomic clocks, superprecise gyroscopes for navigation, and gravity sensors for mapping mineral lodes and oil fields.
This article examines three of the newest and most exciting Einsteinian spin-offs emerging from research labs; more such innovations will certainly follow in the years and decades to come. Although nearly a century has passed since the master physicist began fashioning better mathematical tools to describe the universe, there seems no end to the useful gadgets that clever inventors can make with them.
相对论与自旋 Taking Relativity for a Spin
1905年,爱因斯坦研究狭义相对论时所用的唯一一部计算机,就是装在他脑袋里的那部。在许多方面,那部生化机器要比任何电子计算机厉害得多了。当然,至今还没有任何半导体微处理器,可以和人脑的密度与能源效率相提并论:人脑大约有一公斤重,其中有1000兆个处理单元,可是使用的功率和产生的热量,却比Pentium 4微处理器还要小。
的确,对半导体工业来说,在追求以同样的单位成本制造更高效能微晶片的路途上,热与能源消耗是当今最难以克服的障碍。在未来的20年内,我们熟知的以矽为原料的数位微处理器,将会碰到经济与物理的根本极限。晶片制造商除了转而利用不同物理原理的设计,如狭义相对论之外,也许没有什麼别的选择了。
表面上,这似乎是个古怪的结合。通常我们只会把狭义相对论和高速运动联想在一起。在这个理论中,爱因斯坦抛弃了绝对时间和绝对静止的观念。他断言,唯一的常数是c,也就是光在穿越真空时所拥有的速度。这个定律,为任何高速运动(相对於观察者)的物体带来了奇怪的结果。比如说,该物体的长度会变短,而它所感受到的时间似乎要比观察者的慢。如果物体穿越静电场,它会觉得有一部份的场是磁场。话说回来,这些所谓的相对论效应都很微小,除非物体的速度和c相比很显著,而c大概是每秒三亿公尺。
在这个标准之下,即使是「行动」电脑也不算动得很快。不过电脑里的电子却够快。今年稍早美国加州大学圣巴巴拉分校由奥沙隆(David D. Awschalom)领导的研究群,展示了一种利用相对论的方式,他们让半导体中快速运动的电子,表演出令人印象深刻的新把戏。
这项研究还处於早期阶段,大概类似40几年前造出第一个半导体逻辑闸时的状况。不过假如工程师有办法把几百万个相对论性逻辑闸整合在一小块矽晶片上,其成果可能就是执行速度比当今机种快很多,而功率消耗与热辐射却少得多的微处理器;奥沙隆目前正在和英特尔与惠普的研究群合作研发这种晶片。
更引人注目的是,相对论性晶片可运用比目前所有电脑用的二进位运算更复杂的逻辑。原则上,这些新型机器甚至可以自己调整它们的布线方式,而且几乎在瞬间就可变成专为手中工作所量身订做的电路。举例来说,想像这种行动电话吧,它能重新配置它的无线电收发器,来使用世界上各种网络,而且只要按一个钮,就能重新设定它的微处理器,把一种语言翻译成另外一种。
诸如此类的晶片,在现有的微处理器工厂中制造的可能性非常高。因为秘方并不是新材料,而是近代物理:由相对论和量子力学所描述的行为。
THE ONLY COMPUTER that Einstein used to work out his special theory of relativity in 1905 was the one inside his skull. In many ways, that biochemical machine was far more capable than any electronic computer. Certainly no semiconctor microprocessor yet built can rival the density and energy efficiency of the human brain, which packs roughly a million billion processing elements into a one-kilogram package that uses less power and generates less heat than a Pentium 4 microprocessor.
Indeed, heat and energy consumption today stand as the most formidable obstacles to the semiconctor instry as it seeks to proce ever more powerful microchips at the same unit cost. Within the next 20 years, the advance of digital silicon processors as we know them will hit fundamental economic and physical limits. Chipmakers will have little choice but to move to designs that exploit different principles of physics—those of special relativity, for example.
On its face, that seems an odd combination. Special relativity is all about high-velocity motion. In the theory, Einstein discards the concepts of absolute time and absolute rest. The only constant, he asserts, is c, the speed at which light travels through empty space. That law has strange consequences for any object as it accelerates (relative to the observer). The object's length shortens, for example, and it seems to experience time more slowly than the observer does. If the object moves through a static electric field, it perceives the field as partially magnetic. These so-called relativistic effects are all minuscule, however, unless the object accelerates to a significant fraction of c, which is about 300 million meters per second.
Even “mobile” computers don't move very fast by that standard. But the electrons inside them do. And earlier this year a group of physicists led by David D. Awschalom of the University of California at Santa Barbara demonstrated a way to exploit relativity to make the fast-moving electrons in semiconctors perform impressive new tricks.
The work is at an early stage, roughly analogous to the construction of the first semiconctor logic gate some 40 years ago. But if engineers can figure out how to integrate millions of relativistic gates on a small silicon chip—and Awschalom is working with research groups at Intel and Hewlett-Packard to do just that—the result could be processors that run much faster than current models do, while consuming far less power and radiating far less heat.
Even more dramatically, relativistic chips could employ logic that is more sophisticated than the binary operations all computers now use. In principle, these new machines could even modify the way they are wired, adapting almost instantaneously into a circuit customized for the task at hand. Imagine a cell phone, for example, that can reconfigure its transceiver to use any network in the world and that at the push of a button can reprogram its processor to translate speech from one language to another.
Chips such as these could most likely be made in existing microprocessor factories. The secret ingredient is not some new material, but modern physics—behaviors described by the theories of relativity and quantum mechanics.
磁的吸引力 The Magnetic Attraction
一般传统的半导体微晶片运作的基础,是19世纪的「古典」电磁理论。矽晶圆用离子轰击,而在其上形成微小的岛,各自具有过量或是不足的电子。在这些岛之间布置的微电极上加电压,就能推拉电子进出这些区域、开关逻辑闸,并且调控经过其间的电流。
把大量的邻近电子撞开,是很不精确的:有些电子会凌乱地弹开,而浪费能量;同时也会产生许多碰撞而发热。10多年来,已有物理学家实验过另一类更精密的方式:以磁力代替电场来操纵电子。
美国爱荷华大学的物理学家弗拉提(Micheal E. Flatté)解释道,这个点子行得通,是因为「电子和外界的交互作用,就好像它随身带著一根小小的磁铁棒一样。」磁铁有S极N极。而就和地球绕著连接两极的轴自转一样,每颗电子也都具有磁指向,就是物理学家称为「自旋」的量子性质。这些粒子并非真的在旋转,不过它们的表现确实很像是个小陀螺仪。把磁力加在电子上,电子的两极会开始进动——它的转轴本身会绕圈圈。把磁场拿掉,电子的自旋就定住了(见左页〈磁的魔术〉)。弗拉提说:「利用这种效应,把自旋从指向往上的状态进动到往下,你就可以把电子所带的资讯位元从1变成0。」
电子学以改变电子数量与能量的方式,在电路中移动资讯,而刚萌芽的自旋电子学(spintronics)则将资料编码在电子自旋的指向中,并且用各种扭转自旋的方式来做逻辑运算(2002年9月号〈前途无量的自旋电子〉)。摩托罗拉从今年开始量产一种自旋电子记忆晶片,叫做MRAM(magnetic RAM,磁性随机存取记忆体)。和一般的电脑记忆体不同,MRAM晶片在电源中断时不会损失资料;电源再度打开前,电子的自旋会一直保持在它的指向上。
自旋电子元件很容易用电池驱动,因为自旋反转操作所消耗的能量极其微小,而且晶片在两次运算之间可以停止供应电源。改变一个电子的自旋实际上并不会增加粒子的动能,因此电路几乎不会发热。而且整个程序进行得极快:实验用的装置,只消在几皮秒(10-12秒)以内,就能让电子转头。
不过直到最近,所有的自旋电子元件都得用铁磁金属才行,这和当前微晶片的制造技术并不协调。奥沙隆说:「很难想像你怎麼能在晶片上的几百万个位置添造小磁铁,而且还能各自独立地控制它们;不是不可能啦,只是很困难。运用现有价值几兆元的电子闸极技术会比较好,也就是用电场而非磁场,来操纵自旋。」
CONVENTIONAL SEMICONDUCTOR microchips operate based on “classical” 19th-century theories of electromagnetism. Silicon wafers are zapped with ions, which form tiny islands with either an excess or a dearth of electrons. Voltages, applied to microscopic electrodes built up around these islands, push and pull electrons in and out of these regions, opening and closing the logic gates and regulating the flow of electric current through them.
Shoving large numbers of electrons around is imprecise—some shoot out in random directions, wasting energy—and it creates lots of collisions, which proce heat. For more than a decade now, physicists have been experimenting with a subtler alternative: using magnetic forces, rather than electric fields, to manipulate the electrons.
This can work, explains physicist Michael E. Flatté of the University of Iowa, because “an electron acts as if it carries around with it a little bar magnet.” Magnets have north and south poles, and just as the earth spins around the axis that connects its poles, an electron, too, has a magnetic orientation, a quantum property that physicists call “spin.” The particles don't actually rotate, but they do behave like little gyroscopes. Apply magnetic force to an electron, and its poles will precess—the axis itself rotates in a circle. Remove the field, and the electron holds its spin steady [see box on opposite page]. “By using this effect to precess the spin from pointing up to pointing down, you can change the bit of information carried by that electron from a 1 to a 0,” Flatté says.
Whereas electronics move information around by changing the number and energy of electrons in a circuit, the nascent field of spintronics encodes data in the orientation of electrons and performs logical operations by twisting their spins this way and that [see “Spintronics,” by David D. Awschalom, Michael E. Flatté and Nitin Samarth; Scientific American, June 2002]. This year Motorola began mass-procing spintronic memory chips, called MRAM (for magnetic RAM). Unlike conventional computer memories, the MRAM chips do not lose their data if power is interrupted; the electron spins simply hold their position until power returns.
Spintronic devices are easy on batteries, because spin-flipping operations consume very little power and the chips can shut off between operations. Changing an electron's spin adds virtually no kinetic energy to the particle, so the circuits proce almost no heat. And the process is exceedingly fast: experimental devices have turned electrons on their heads in a few picoseconds (trillionths of a second).
Until recently, however, all spintronic devices have required ferromagnetic metals, which do not mesh well with current microchip proction techniques. “It's difficult to imagine how you could build little magnets at millions of places on a chip and control each one indivially—not impossible, but difficult,” Awschalom says. “It would be much nicer to use the trillions of dollars' worth of electronics gating technology that already exists and to use electric fields, not magnetic fields, to play with spins.”
突破0与1的限制 From Bits to Phits
现在要进入爱因斯坦与他的奇怪想法了:对一个高速运动的电子来说,部份电场看起来会变成截然不同的磁场。在今年1月发表的研究工作中,奥沙隆的研究群就展示了,若将两层成份稍有不同的半导体叠起来,晶片的应变会造成一个内部的电场。当电子通过半导体时,这电场的高低分布就像围栏一样把电子驱赶在一起。他解释:「由於相对论的关系,由正在穿越的电子看来,这电场会有一部份像是磁场。」於是电子的自旋开始像摇晃的陀螺般进动。
「我们可以用两种方式来控制电子。」奥沙隆继续说,「一种方式是改变电压,这会影响到电子穿越的速度。它们跑得越快,看到的有效磁场越大,」而自旋就进动得越快。第二种手段是利用应变在各方向上的不同性。他说:「我们也可以仔细地设计用来规范电子路径的线路形状和方向。」
在1月的论文中,该研究群描述了如何运用雷射光脉冲来排列入射电子的指向,以造出自旋电子位元,以及如何测量它们的自旋。「下一步是在同一个电子装置中造出它们,把它们四处移动,并且侦测到它们全部。那是相当重要的一步,而我们现在已经办到了,」奥沙隆说,「这个装置和目前电脑中的CMOS晶片使用一样的电压。当电子撞击到半导体应变的部份时,自旋会在瞬间极化。然后我们就可以同调地上下翻转它们的自旋。」这用的是开关闸极的方式。
「同调」是这里的关键字,因为它提出了自旋电子晶片最有趣的可能性:超越只有0与1两个数字的位元,而达到相位元(phase digit, phit)的境界,而有更大范围的数值可取。电子的相位就是它自旋所指向的方向。把它想成罗盘的指针好了:假如微晶片可以分辨一群群自旋分别指向东、西、南、北方向的电子,那麼每个相位元就可以是0或1、或2或3。
奥沙隆指出:「相位读得越精确,你就可以把资料储存的密度增加得越夸张。至於增加50还是一万倍,端看你测量那个角度有多精确。」感谢几十年来侦测原子核自旋的磁共振造影技术的发展,「我们确实知道怎麼把这些角度量得很准。」他补上一句。
即使如此,弗拉提警告说:「一个完整可用的自旋电晶体尚未发展成功。」电晶体是不可或缺的,因为它能放大信号,使信号在微处理器中原封不动地穿过一长串逻辑闸。不过虽然依据自旋电子学设计的电晶体目前还不存在,却显然会在不久的将来诞生,研究者也正热切地计画著用他们来做些什麼事。
去年,德国柏林德鲁得固态电子研究所的柯克(Reinhold Koch)与他的研究群,发表了一个运用自旋电子逻辑元件的设计,它能在软体的控制下改变自己的功能。在某个时刻它可以是布林(Boolean)运算的AND闸,几奈秒(10-9秒)之后,它又可以转变成一个OR闸、NOR闸或NAND闸。
能在一瞬间重新布线的电脑,的确威力强大。柯克最近设计了一个完整的加法器(电脑逻辑单元里最普通的一种),其中只用到了四个自旋逻辑元件,而非通常所需要的16个电晶体。自旋电子版的加法器可以节省85%的能源以及75%的空间,执行的速度却和当今最顶级的微晶片设计一样快。
工程师距离能得心应手地运用相对论来当成自旋电子电路的设计工具,还差很远。不过在现有道路上充满障碍的情况下,爱因斯坦的理论却也能为电脑工业另辟蹊径。奥沙隆说:「对这里的物理有一项有趣的观点是,元件越小,工作得越好。」
ENTER EINSTEIN and his curious notion that an electric field can look distinctly magnetic to a high-speed electron. In work published this past January, Awschalom's group showed that layering two semiconctors of slightly different composition on top of one another strains the chip in ways that set up an internal electric field. The field has high and low spots that act like a corral to herd electrons as they pass through the semiconctor. “And because of relativity, that electric field looks like a partially magnetic field to the passing electrons,” he notes. The electrons' spins start to precess like wobbly gyroscopes.
“We can control the electrons in two ways,” Awschalom continues. “One way is to change the voltage, which affects the speed at which the electrons travel. The faster they move, the larger the effective magnetic field seems to them” and the faster their spins precess. The second trick exploits the fact that the strain varies with direction. “We can also operate on electrons by carefully designing the shape and direction of the wire that sets their path,” he says.
In the January paper, the group described using pulses of laser light to align the orientation of incoming electrons—thus creating the spintronic bits—as well as to measure their spins. “The next step is to create them, move them around and detect them all in one electric device. That's a substantial step, but we've done that now,” Awschalom reports. “The device uses the same small voltages currently used in CMOS computer chips. Electrons instantaneously polarize their spins when they hit the strained part of the semiconctor. We can then flip their spins back and forth coherently” by turning gate electrodes on or off.
“Coherently” is the key word here, because it raises the intriguing possibility of spintronic chips that go beyond bits—the binary digits 0 and 1—to “phits,” or phase digits, which can take on a wider range of values. The phase of an electron is simply the direction in which its spin points. Think of it as the needle of a compass: if a microchip can distinguish groups of electrons with north-, south-, east- and west-pointing spins, then each phit could be a 0 or a 1—or a 2 or a 3.
“The more precisely you can read the phase, the more dramatically you can increase the density of data storage,” Awschalom points out. “Whether it increases by a factor of 50 or by 10,000 depends on how precisely you can read that angle.” Thanks to decades of wo
