If users checks function declaration, it has no clue which arguments are meant as input (unchanged on exit) and which are outputFUNCTION ARGUMENTSUser has "no direct contact" with data structures. User might not be aware of data handling. Python is optimized for speed -> references. COPYING DATA>>> a=[1,2,3,[4,5]] >>> b=a[:]>>> a[0]=2>>> b[1,2,3,[4,5]]>>> a[3][0]=0>>> b[1,2,3,[0,5]]# Can be fixed by>>> import copy>>> a=[1,2,3,[4,5]] >>> b = copy.deepcopy(a) >>> a[3][0]=0>>> b[1,2,3,[4,5]]Criticism of PythonCLASS DATAIn C++ class declaration uncovers all important information about the class -class members (data and methods). In Python, data comes into existence when used. User needs to read implementation of the class (much more code) to find class data and understand the logic of the class. This is particularly important in large scale codes.RELODING MODULESIf you import a module in command-line interpreter, but the module was later changed on disc, you can reload the module by typingreload modulexxxThis reloads the particular modulexxx, but does not recursively reload modules that might also be changed on disc and are imported by the modulexxx.NumPyNumPyand SciPy>>> from numpy import *>>> import numpy>>> numpy.__version__’1.0.1’or better>>> from scipy import *>>> import scipy>>> scipty.__version__'0.5.2'IMPORT NUMPY AND SCIPYArray Operations>>> a = array([1,2,3,4])>>> b = array([2,3,4,5])>>> a + barray([3, 5, 7, 9])# Create array from 0 to 10>>> x = arange(11.)# multiply entire array by # scalar value>>> a = (2*pi)/10.>>> a0.628318530718>>> a*xarray([ 0.,0.628,…,6.283])# apply functions to array.>>> y = sin(a*x)SIMPLE ARRAY MATH MATH FUNCTIONSconstants:Introducing Numeric Arrays>>> a = array([0,1,2,3])>>> aarray([0, 1, 2, 3])SIMPLE ARRAY CREATION >>> type(a)<type 'array'>CHECKING THE TYPE >>> a.typecode()'l‘# ‘l’= Int NUMERIC TYPE OF ELEMENTS >>> a.itemsize()4BYTES IN AN ARRAY ELEMENT >>> a.shape (4,)>>> shape(a)(4,)ARRAY SHAPE >>> a.tolist()[0, 1, 2, 3]CONVERT TO PYTHON LIST >>> a[0]0>>> a[0] = 10>>> a[10, 1, 2, 3]ARRAY INDEXING>>> a[13>>> a[1,3] = -1>>> aarray([[ 0, 1, 2, 3],[10,11,12,-1]])Multi-Dimensional Arrays>>> a = array([[ 0, 1, 2, 3],[10,11,12,13]])>>> aarray([[ 0, 1, 2, 3],[10,11,12,13]])>>> a[1]array([10, 11, 12, 13])rowcolumn MULTI-DIMENSIONAL ARRAYS >>> shape(a)(2, 4)(ROWS,COLUMNS)GET/SET ELEMENTS ADDRESS FIRST ROW USING SINGLE INDEXFLATTEN TO 1D ARRAY A.FLAT AND RAVEL() REFERENCE ORIGINAL MEMORY>>> a.flatarray(0,1,2,3,10,11,12,-1)>>> ravel(a)array(0,1,2,3,10,11,12,-1)>>> a.flat[5] = -2>>> aarray([[ 0, 1, 2, 3],[10,-2,12,-1]])Array Slicing>>> a[0,3:5]array([3, 4])>>> a[4:,4:]array([[44, 45],[54, 55]])>>> a[:,2]array([2,12,22,32,42,52])SLICING WORKS MUCH LIKE STANDARD PYTHON SLICING >>> a[2::2,::2]array([[20, 22, 24],[40, 42, 44]])STRIDES ARE ALSO POSSIBLESlices Are References>>> a = array([0,1,2])# create a slice containing only the # last element of a >>> b = a[2:3] >>> b[0] = 10# changing b changed a!>>> aarray([ 1, 2, 10])Slices are references to memory in original array.

informationPrefaceQuantum computing is a fascinating newfield at the intersection of computer sci-ence,mathematics,and physics,which strives to harness some of the uncanny as-pects of quantum mechanics to broaden our computational horizons.This bookpresents some of the most exciting and interesting topics in quantum computing.Along the way,there will be some amazing facts about the universe in which we liveand about the very notions of information and computation.The text you hold in your hands has a distinctflavor from most of the other cur-rently available books on quantum computing.First and foremost,we do not assumethat our reader has much of a mathematics or physics background.This book shouldbe readable by anyone who is in or beyond their second year in a computer scienceprogram.We have written this book specifically with computer scientists in mind,and tailored it accordingly:we assume a bare minimum of mathematical sophistica-tion,afirst course in discrete structures,and a healthy level of curiosity.Because thistext was written specifically for computer people,in addition to the many exercisesthroughout the text,we added many programming drills.These are a hands-on,funway of learning the material presented and getting a real feel for the subject.The calculus-phobic reader will be happy to learn that derivatives and integrals are virtually absent from our text.Quite simply,we avoid differentiation,integra-tion,and all higher mathematics by carefully selecting only those topics that arecritical to a basic introduction to quantum computing.Because we are focusing onthe fundamentals of quantum computing,we can restrict ourselves to thefinite-dimensional mathematics that is required.This turns out to be not much more thanmanipulating vectors and matrices with complex entries.Surprisingly enough,thelion’s share of quantum computing can be done without the intricacies of advancedmathematics.Nevertheless,we hasten to stress that this is a technical textbook.We are not writing a popular science book,nor do we substitute hand waving for rigor or math-ematical precision.Most other texts in thefield present a primer on quantum mechanics in all its glory.Many assume some knowledge of classical mechanics.We do not make theseassumptions.We only discuss what is needed for a basic understanding of quantumxiMore informationxii Prefacecomputing as afield of research in its own right,although we cite sources for learningmore about advanced topics.There are some who consider quantum computing to be solely within the do-main of physics.Others think of the subject as purely mathematical.We stress thecomputer science aspect of quantum computing.It is not our intention for this book to be the definitive treatment of quantum computing.There are a few topics that we do not even touch,and there are severalothers that we approach briefly,not exhaustively.As of this writing,the bible ofquantum computing is Nielsen and Chuang’s magnificent Quantum Computing andQuantum Information(2000).Their book contains almost everything known aboutquantum computing at the time of its publication.We would like to think of ourbook as a usefulfirst step that can prepare the reader for that text.FEATURESThis book is almost entirely self-contained.We do not demand that the reader comearmed with a large toolbox of skills.Even the subject of complex numbers,which istaught in high school,is given a fairly comprehensive review.The book contains many solved problems and easy-to-understand descriptions.We do not merely present the theory;rather,we explain it and go through severalexamples.The book also contains many exercises,which we strongly recommendthe serious reader should attempt to solve.There is no substitute for rolling up one’ssleeves and doing some work!We have also incorporated plenty of programming drills throughout our text.These are hands-on exercises that can be carried out on your laptop to gain a betterunderstanding of the concepts presented here(they are also a great way of hav-ing fun).We hasten to point out that we are entirely language-agnostic.The stu-dent should write the programs in the language that feels most comfortable.Weare also paradigm-agnostic.If declarative programming is your favorite method,gofor it.If object-oriented programming is your game,use that.The programmingdrills build on one another.Functions created in one programming drill will be usedand modified in later drills.Furthermore,in Appendix C,we show how to makelittle quantum computing emulators with MATLAB or how to use a ready-madeone.(Our choice of MATLAB was dictated by the fact that it makes very easy-to-build,quick-and-dirty prototypes,thanks to its vast amount of built-in mathematicaltools.)This text appears to be thefirst to handle quantum programming languages in a significant way.Until now,there have been only research papers and a few surveyson the topic.Chapter7describes the basics of this expandingfield:perhaps some ofour readers will be inspired to contribute to quantum programming!This book also contains several appendices that are important for further study:Appendix A takes readers on a tour of major papers in quantum computing.This bibliographical essay was written by Jill Cirasella,Computational SciencesSpecialist at the Brooklyn College Library.In addition to having a master’s de-gree in library and information science,Jill has a master’s degree in logic,forwhich she wrote a thesis on classical and quantum graph algorithms.This dualbackground uniquely qualifies her to suggest and describe further readings.More informationPreface xiii Appendix B contains the answers to some of the exercises in the text.Othersolutions will also be found on the book’s Web page.We strongly urge studentsto do the exercises on their own and then check their answers against ours.Appendix C uses MATLAB,the popular mathematical environment and an es-tablished industry standard,to show how to carry out most of the mathematicaloperations described in this book.MATLAB has scores of routines for manip-ulating complex matrices:we briefly review the most useful ones and show howthe reader can quickly perform a few quantum computing experiments with al-most no effort,using the freely available MATLAB quantum emulator Quack.Appendix D,also by Jill Cirasella,describes how to use online resources to keepup with developments in quantum computing.Quantum computing is a fast-movingfield,and this appendix offers guidelines and tips forfinding relevantarticles and announcements.Appendix E is a list of possible topics for student presentations.We give briefdescriptions of different topics that a student might present before a class of hispeers.We also provide some hints about where to start looking for materials topresent.ORGANIZATIONThe book begins with two chapters of mathematical preliminaries.Chapter1con-tains the basics of complex numbers,and Chapter2deals with complex vectorspaces.Although much of Chapter1is currently taught in high school,we feel thata review is in order.Much of Chapter2will be known by students who have had acourse in linear algebra.We deliberately did not relegate these chapters to an ap-pendix at the end of the book because the mathematics is necessary to understandwhat is really going on.A reader who knows the material can safely skip thefirsttwo chapters.She might want to skim over these chapters and then return to themas a reference,using the index and the table of contents tofind specific topics.Chapter3is a gentle introduction to some of the ideas that will be encountered throughout the rest of the ing simple models and simple matrix multipli-cation,we demonstrate some of the fundamental concepts of quantum mechanics,which are then formally developed in Chapter4.From there,Chapter5presentssome of the basic architecture of quantum computing.Here one willfind the notionsof a qubit(a quantum generalization of a bit)and the quantum analog of logic gates.Once Chapter5is understood,readers can safely proceed to their choice of Chapters6through11.Each chapter takes its title from a typical course offered in acomputer science department.The chapters look at that subfield of quantum com-puting from the perspective of the given course.These chapters are almost totallyindependent of one another.We urge the readers to study the particular chapterthat corresponds to their favorite course.Learn topics that you likefirst.From thereproceed to other chapters.Figure0.1summarizes the dependencies of the chapters.One of the hardest topics tackled in this text is that of considering two quan-tum systems and combining them,or“entangled”quantum systems.This is donemathematically in Section2.7.It is further motivated in Section3.4and formallypresented in Section4.5.The reader might want to look at these sections together.xivPrefaceFigure 0.1.Chapter dependencies.There are many ways this book can be used as a text for a course.We urge instructors to find their own way.May we humbly suggest the following three plans of action:(1)A class that provides some depth might involve the following:Go through Chapters 1,2,3,4,and 5.Armed with that background,study the entirety of Chapter 6(“Algorithms”)in depth.One can spend at least a third of a semester on that chapter.After wrestling a bit with quantum algorithms,the student will get a good feel for the entire enterprise.(2)If breadth is preferred,pick and choose one or two sections from each of the advanced chapters.Such a course might look like this:(1),2,3,4.1,4.4,5,6.1,7.1,9.1,10.1,10.2,and 11.This will permit the student to see the broad outline of quantum computing and then pursue his or her own path.(3)For a more advanced class (a class in which linear algebra and some mathe-matical sophistication is assumed),we recommend that students be told to read Chapters 1,2,and 3on their own.A nice course can then commence with Chapter 4and plow through most of the remainder of the book.If this is being used as a text in a classroom setting,we strongly recommend that the students make presentations.There are selected topics mentioned in Appendix E.There is no substitute for student participation!Although we have tried to include many topics in this text,inevitably some oth-ers had to be left out.Here are a few that we omitted because of space considera-tions:many of the more complicated proofs in Chapter 8,results about oracle computation,the details of the (quantum)Fourier transforms,and the latest hardware implementations.We give references for further study on these,as well as other subjects,throughout the text.More informationMore informationPreface xvANCILLARIESWe are going to maintain a Web page for the text at/∼noson/qctext.html/The Web page will containperiodic updates to the book,links to interesting books and articles on quantum computing,some answers to certain exercises not solved in Appendix B,anderrata.The reader is encouraged to send any and all corrections tonoson@Help us make this textbook better!ACKNOLWEDGMENTSBoth of us had the great privilege of writing our doctoral theses under the gentleguidance of the recently deceased Alex Heller.Professor Heller wrote the follow-ing1about his teacher Samuel“Sammy”Eilenberg and Sammy’s mathematics:As I perceived it,then,Sammy considered that the highest value in mathematicswas to be found,not in specious depth nor in the overcoming of overwhelmingdifficulty,but rather in providing the definitive clarity that would illuminate itsunderlying order.This never-ending struggle to bring out the underlying order of mathematical structures was always Professor Heller’s everlasting goal,and he did his best to passit on to his students.We have gained greatly from his clarity of vision and his viewof mathematics,but we also saw,embodied in a man,the classical and sober ideal ofcontemplative life at its very best.We both remain eternally grateful to him.While at the City University of New York,we also had the privilege of inter-acting with one of the world’s foremost logicians,Professor Rohit Parikh,a manwhose seminal contributions to thefield are only matched by his enduring com-mitment to promote younger researchers’work.Besides opening fascinating vis-tas to us,Professor Parikh encouraged us more than once to follow new directionsof thought.His continued professional and personal guidance are greatly appre-ciated.We both received our Ph.D.’s from the Department of Mathematics in The Graduate Center of the City University of New York.We thank them for providingus with a warm and friendly environment in which to study and learn real mathemat-ics.Thefirst author also thanks the entire Brooklyn College family and,in partic-ular,the Computer and Information Science Department for being supportive andvery helpful in this endeavor.1See page1349of Bass et al.(1998).More informationxvi PrefaceSeveral faculty members of Brooklyn College and The Graduate Center were kind enough to read and comment on parts of this book:Michael Anshel,DavidArnow,Jill Cirasella,Dayton Clark,Eva Cogan,Jim Cox,Scott Dexter,EdgarFeldman,Fred Gardiner,Murray Gross,Chaya Gurwitz,Keith Harrow,JunHu,Yedidyah Langsam,Peter Lesser,Philipp Rothmaler,Chris Steinsvold,AlexSverdlov,Aaron Tenenbaum,Micha Tomkiewicz,Al Vasquez,Gerald Weiss,andPaula Whitlock.Their comments have

q-emulator Quack and also for letting us use it in our appendix.We had a gooddeal of fun playing with it,and we hope our readers will too.Besides writing two wonderful appendices,our friendly neighborhood librar-ian,Jill Cirasella,was always just an e-mail away with helpful advice and support.Thanks,Jill!A very special thanks goes to our editor at Cambridge University Press,HeatherBergman,for believing in our project right from the start,for guiding us through thisbook,and for providing endless support in all matters.This book would not existwithout her.Thanks,Heather!We had the good fortune to have a truly stellar editor check much of the text many times.Karen Kletter is a great friend and did a magnificent job.We also ap-preciate that she refrained from killing us every time we handed her altered draftsthat she had previously edited.But,of course,all errors are our own!This book could not have been written without the help of my daughter,Hadas-sah.She added meaning,purpose,and joy.N.S.Y.My dear wife,Rose,and our two wondrous and tireless cats,Ursula and Buster, contributed in no small measure to melting my stress away during the long andpainful hours of writing and editing:to them my gratitude and love.(Ursula is ascientist cat and will read this book.Buster will just shred it with his powerful claws.)M.A.M.。

/ 电子技术论坛 电子发烧友第一章: 第一章:范例在这一章里将提供三个范例来说明如何使用 C/OS-II。

笔者之所以在本书一开始就写 这一章是为了让读者尽快开始使用 C/OS-II。

在开始讲述这些例子之前,笔者想先说明一 些在这本书里的约定。

这些例子曾经用 Borland C/C++ 编译器(V3.1)编译过,用选择项产生 Intel/AMD80186 处理器(大模式下编译)的代码。

这些代码实际上是在 Intel Pentium II PC (300MHz)上 运行和测试过,Intel Pentium II PC 可以看成是特别快的 80186。

笔者选择 PC 做为目标系 统是由于以下几个原因:首先也是最为重要的,以 PC 做为目标系统比起以其他嵌入式环境, 如评估板,仿真器等,更容易进行代码的测试,不用不断地烧写 EPROM,不断地向 EPROM 仿 真器中下载程序等等。

用户只需要简单地编译、链接和执行。

其次,使用 Borland C/C++产 生的 80186 的目标代码(实模式,在大模式下编译)与所有 Intel、AMD、Cyrix 公司的 80x86 CPU 兼容。

1.00 安装 C/OS-II C/OS本书附带一张软盘包括了所有我们讨论的源代码。

是假定读者在 80x86,Pentium,或者 Pentium-II 处理器上运行 DOS 或 Windows95。

至少需要 5Mb 硬盘空间来安装 uC/OS-II。

请按照以下步骤安装: 1.进入到 DOS(或在 Windows 95 下打开 DOS 窗口)并且指定 C:为默认驱动器。

2.将磁盘插入到 A:驱动器。

3.键入 A:INSTALL 【drive】 注意『drive』是读者想要将 C/OS-II 安装的目标磁盘的盘符。

INSTALL.BAT 是一个 DOS 的批处理文件,位于磁盘的根目录下。

它会自动在读者指定的 目标驱动器中建立\SOFTWARE 目录并且将 uCOS-II.EXE 文件从 A: 驱动器复制到\SOFTWARE 并 且运行。
