What happens if you throw a tennis ball at a brick wall?
What if you threw a hundred tennis balls at the wall at the same time?
What if you threw a thousand tennis balls?
Nothing.

No matter what you do, there’s no way tennis balls are going to break down that brick wall. [...]]]></description>

<p>No matter what you do, there’s no way tennis balls are going to break down that brick wall. Just like a brick wall, there are some problems that are so complex that there’s no way a traditional computer, no matter how fast, can solve them.</p>
<p>But what happens to the brick wall if you drive a tank through it?</p>
<p>No more brick wall.</p>
<p>That tank is a quantum computer.</p>
<p>Bits and Qubits</p>
<p><span id="more-305"></span><br />
Classical computers, the kind we use every day, use memory made up of bits. Bits represent either one or zero; on or off. Everything computers do, from playing games to sending email, comes from manipulating those ones and zeros.</p>
<p>A quantum computer is a new type of computer that uses the unusual properties of quantum physics to solve problems that are impossible for regular computers. They do this by using qubits instead of bits. Like bits, qubits can represent a one or zero. What makes them special is that a qubit can be one, zero or a superposition of both. That means that a qubit can be both one and zero at the same time – making quantum computers exponentially more powerful than their conventional counterparts.</p>
<p>Breaking the Brick Wall</p>
<p>By using superposition, quantum computers can solve problems that would be impossible or take thousands of years to complete. Quantum computers dramatically outperform classical computers in calculations involving large numbers of equally possible solutions.</p>
<p>Because of their strength at analyzing combinations, quantum computers will most likely be applied to breaking codes and optimizing complex systems. Researchers also expect that quantum computers will be able to accurately model events at the molecular scale, providing a powerful tool for biology, chemistry, and physics research.</p>
<p>Problems and Predictions</p>
<p>Superposition is powerful, mysterious and delicate. The biggest barrier to building fully functioning quantum computers is that qubits must be held in a super-cooled, isolated state or they decohere and loose their quantum “magic.”</p>
<p>Quantum computers are sitting at the edge of practicality. Developers have successfully constructed working quantum computers, but so far have been unable to get enough qubits working at the same time to realize their full potential – but the promise of that potential has scientists all over the world working on making quantum computing one of the defining technologies of the 21st century.</p>

<div id="body">
<p>It is often a fancy idea and an interesting endeavor even to think of the theory of everything leave alone find one, yet it is an adventure in the search and indeed it was an adventure unlike any. It is an adventure in to the inner depth and in to the fundamentals of the beginning itself and the stuff it was and is made of and how.</p>
<p><object id="Player_72201d17-e115-4092-8d9b-7b8a2745d021" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="300" height="250" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"><param name="quality" value="high" /><param name="bgcolor" value="#FFFFFF" /><param name="allowscriptaccess" value="always" /><param name="src" value="http://ws.amazon.com/widgets/q?ServiceVersion=20070822&amp;MarketPlace=US&amp;ID=V20070822%2FUS%2Fgranddollar-20%2F8003%2F72201d17-e115-4092-8d9b-7b8a2745d021&amp;Operation=GetDisplayTemplate" /><param name="name" value="Player_72201d17-e115-4092-8d9b-7b8a2745d021" /><param name="align" value="middle" /><embed id="Player_72201d17-e115-4092-8d9b-7b8a2745d021" type="application/x-shockwave-flash" width="300" height="250" src="http://ws.amazon.com/widgets/q?ServiceVersion=20070822&amp;MarketPlace=US&amp;ID=V20070822%2FUS%2Fgranddollar-20%2F8003%2F72201d17-e115-4092-8d9b-7b8a2745d021&amp;Operation=GetDisplayTemplate" align="middle" name="Player_72201d17-e115-4092-8d9b-7b8a2745d021" allowscriptaccess="always" bgcolor="#FFFFFF" quality="high"></embed></object></p>
<p>The adventure to the past in search of the beginning is as much a time travel to the past as much it is a time travel to the future that it may be only at the end that we truly find the meaning and the true stuff it was made of, for when the end somewhat becomes the beginning the knowledge, the essence and being of the two will merge. At such a time, there shall be no matter but</p>
<p><span id="more-97"></span></p>
<p>information or knowledge and there shall be no process unknown everything from the beginning to the end and everything from the end to the beginning have been a matter of recorded history. Till such time the end and start converge, due to the curse and blessing we are burdened with we have to continue in the search and the adventure of discovery to fill in the gaps and blanks that will only cease most likely when everything else and all ceases, is nothing and no more. In that we could be saying the totality of what is, is nothing more than what we can imagine and we are capable of imagining in an open ended extension even not bounded by negative and positive infinity for even infinity and zero which are analogues concepts. Zero and infinity as all numbers are values but none descript existent but not reachable as examples and manifestation of ever continuity. In a way the digital world of mathematics and physical sciences and the analogues world of the arts philosophy and religion seems to merge somewhere at the end of our journey and the beginning of everything and ours at infinity and at zero in apparent breach of our ineptitude to imagine and cognize beyond what is as our basis. After all we might have been thinking of the dual characteristics of matter and reality itself as analogues waves and digitized particles as separately and distinctly instead of dualities as we have long concluded of light as what is an established reality. The digital world outlook and the Mathematical model by in large is a model that fails to fill in all the gaps and leaves space between the gaps and leaves everything to the best possible approximations and its world and universe crisp and noise free contrary to the noisy and continues Universe and reality. We may attribute the greatest of contribution to digitize and sanitize the universe and reality to calculus&#8217;s limit in a great recognition of its limits in spite of all its monumental accomplishments in translating the Universe and reality to an understandable and working entity. It is the noisiness and continuity of the universe and the ineptitude of mathematics to be exact and as continuous the one and the fundamental challenge of reaching the fundamental which simply becomes a mathematical (+infinity) unreachable as that. On the hand our individual and collective descript life with a seemingly defined beginning and end imposes on us to find and search a beginning and end to everything there is yet on the contrary past shape, form and content our own beginning extends beyond we could thus far say, see, hear and touch with the beginnings of everything which could have been pure knowledge (information) upon which the material world constructed itself. The issue then becomes whether this stage of pure knowledge or information is attainable and if superstrings are pure information and knowledge or material constructs of this precedent information and knowledge. In fact Schwarz&#8217;s and Green&#8217;s base their theory on the assertion that super strings are not even point particles rather are extended objects like strings that rotate, spin and vibrate in an apparent separation of space and matter with the space in which these extended particles rotate spin and vibrate by a force field. Devoid of this field there wouldn&#8217;t be space.</p>
<p>It therefore would be easier to speculate whether yet the fundamental lies within this field that is instrumental for the manifestation of space and may be time along with it or as a dual unity of the suspended particles and these force fields. &#8220;Einstein taught that space-time is curved and deformed by the presence of matter and energy. Whenever matter and energy is present, Einstein&#8217;s equations allow physicists to calculate the new curved geometry of space -time. But the curious thing is that they permit for a curvature even when no matter or energy is around.&#8221; There are two things that bothered me the most in the above quotation as a non mathematician and a lay man the first one being that ability to imagine an empty Universe and the second one is the ability of the mathematics to have preceded the universe itself to have been able to calculate this cosmological constant even in the absence of a universe( an empty universe is to me a no universe). It seems to me most or all mathematical equations are subject to conditions in their formulation and execution and wondered if one of the conditions for this equation to work and be true is that there can be no empty universe or if the assertion is made in the pre unI find a lot of filled blanks and gaps in this book as I tried to travel in to the inner depths of the far beginnings of ours and everything we have thus far known and will ever know. Over all I would say for a lay man of my background and average caliber, it was worthy of a reading and a challenge filled thriller. It is as usual from this lay man&#8217;s perspective that I often raise may be some naive even some downright stupid questions and draw some conclusions and may sometimes even come up with some idiotic conjunctures . It is with deep respect for the author and understanding of my rights to agree and disagree with whatever was written and illustrated in the book and the rights of others towards mine and with my report, in search of answers, enlightenment and understanding that I take the monumental task of reviewing this book and writing this report.</p>

<p>In our search of the fundamental beginning of everything and we have often been convinced of reaching it no sooner than we found ourselves in breach once and again. This reach of the fundamental and beginning has always been a mirage that often dissolves in to the thin air no sooner than we concluded that it indeed was what we thought it to be. Armed with that history and the ever expanding human reach beyond its current reach, as &#8220;current&#8221; recedes in to the past and &#8220;future&#8221; makes headway in to the present; with skepticism and doubt that it indeed is the final frontier and with certainty that it indeed is a new breach to what has thus far been known and believed, I would like to lead you in to the layman&#8217;s simplistic journey to the complex Nano world and beyond, to the ultimate minuteness itself.</p>
<p>As you might have seen and read a number of times describing myself as a lay man not from the fear of criticism or the luck of spine to withstand one, rather to emphasize the enormity of the subject matter and how little and ignorant one could be in light of the material under study. After all it is a subject matter that is beyond the reach and an imagination past what we can imagine that we are discussing and often fail short of imagining to imagining what preceded the imagination if at all possible. Or perhaps we are able to imagine beyond the extensions of our individual and collective experience unbounded at all or however hard we try we are simply bound by what we have known and what is out there in the objective world&#8217;s possible extensions at the most. It is mathematical deductions inductions and abstraction alright, yet still beyond what scientific methods calls for the verification authentication and conclusion of a scientific reality at least not yet for we are imagining beyond the reach of our current sensual extenders. May be it would seem we have been caught up with arrogance of what is beyond the most possible extensions of our experience, knowledge and reach of our current available sensual extendersiversal beginning then talk of the empty universe somewhat becomes irrelevant.</p>
<p>To me the universe from its initial beginning to its final demise is full if there are such beginnings and ends, what is it that fills it may be open to examination, speculation, determination quantification and qualification but its fullness a self evident reality beyond question and the mathematical equation that allowed curvature in the &#8220;absence of matter &#8220;is not a proof of the absence as asserted rather a proof of material presence in whatever form and state; a form and a state that could take some time of our future and a distance to be covered for its discovery and determination. As to the assertion of Stephen Haw king&#8217;s matter being created out of the fabrics of space time itself it still does not preclude the existence of a universe filled with space time fabrics but matter, which in effect voids the concept of void or may be space time is equal to void? If that is contrary to the thought of man creating the concept of time-space out of the fringes of its Neurons rather its neurons gave meaning to an already existent reality and a reality that preceded it. As neurons existed in space-time, may be space time existed in all reality as a precursor to itself as the following quote from the book testifies to this duality of reality and reality of duality and ever continuous divisibility.</p>
<p>&#8220;The classification in to fermions and bosons is relevant in another way. Fermions make up the material side of the Universe, while Bosons are responsible for its force. Physicists call bosons the carriers of the weak-strong and electromagnetic forces it is hypothesized of the gravitational force.&#8221; Even our reach of the very minutest of forms of matter seems to have either carrier or yet manifestations of other forms as are gravity in bosons and bosons in gravity or yet in vibrating, rotating and spinning super strings only to reach at a final destination of our quest if only this super strings were to rotate and vibrate in a unit space time for rotation, vibration and even spinning presupposes space time, yet still posing the challenges of discovering what this space time in which these rotations and vibrations happen is and is made of or simply what constitutes it. May be is worth to pose and examine some wise word of the bible here which tells us not to think beyond which we can&#8217;t and take the words without further question as though we could surpass our limits to question or experience . Nonetheless the early acknowledgement of or limitations beyond which we simply part by faith not by any established facts and truths however hard we try to dissociate or associate from the word faith. That seems to be a one convergence point and simultaneously divergent point for the Idealists and materialists to start to traverse their independent paths and come to. That could be why it seems that we have twos of many things for a full Unum, seemingly contradictory, on the opposite sides, and going in opposite directions, yet balancing and equilibrating from and at these fulcrums of convergence and divergence points.</p>
<p>As it is often said and I have been accused of not having the guts and will to take a side to advocate for, I have often said and say it know, none has the total monopoly to the ways and the spectacle with which we can observe the universe and reality to date and the real universe, and reality lies somewhere down the middle if only stripped of personal interests. That for sure is a gut wrenching stand to take for we are all created or evolved to be with un indelible fact of self interest that may not even be limited to us or even living things. Excuses if I sound a person on a double road, I do understand and I am mind full of the fact that the two roads traverse different terrains with different challenges, but I am confining my thoughts and argument only to the points of origin and terminal. If I may take a procedural note of caution I seem to have been derailed from the subject of our discussion which is theoretical and may be practical physics, as we lay men often get mixed up with all things from all cross boundaries taboos and creeds unabated by the stiff brittle disciplines of professionalism, before any one shouts fouls, I extend my apologies and make it clear that it was not at all intentional.</p>

<p>We don&#8217;t need to understand quantum physics entirely in order to appreciate it. Even those who have devoted their lives to the study of the universe and its atomic structure will admit that many mysteries remain. Well, I love mysteries, so let&#8217;s set the scene for this one&#8230;</p>
<p>There&#8217;s a Big Bang. &#8220;Whoosh!&#8221; go all the molecules. Much swirling commences. Fast forward 12 billion years (give or take a billion) to present day. People all over the world watch sci-fi movies, read physics texts, attend harmonic convergence gatherings, study nanotechnology, and gaze at the stars. Our questions: How did we get here? Who are we? Where is here? Why? What next?</p>

<p>If you’re expecting quantum theory to answer those questions, you’re going to be disappointed. However, it does give us some heady new ways to anticipate those answers.</p>
<p><span id="more-52"></span></p>
<p>Let’s take a look at some terms. Back in the fifth century BC, our Greek friend Democritus had the idea that all matter is ultimately made up of tiny grains that cannot be divided into smaller pieces. He called these little pieces “atoms” for the Greek phrase “a-tomos” which means “uncuttable”. Poor Democritus didn’t have the advantage of sophisticated microscopes, so it’s not surprising that, centuries later, it was discovered that atoms are actually cuttable. In fact, atoms are themselves made up of tiny particles we’ve dubbed neutrons, protons, electrons and neutrinos.</p>
<p align="center">
<p>But it doesn’t stop there. Now we’re thinking that leptons, along with quarks, are the tiniest of particles of all and currently considered the ultimate building blocks of nature. Since we keep finding particles inside particles and adding new names to pieces of atoms, it’s easier to refer to the smallest chunks into which something can be divided as quanta. The German physicist Max Planck first proposed that energy might come in little pieces called quanta back in the early 1900s. So when we talk about quantum theory, we’re just referring to the whole set of ideas surrounding the microscopic world of atoms.</p>
<p>Along comes Albert Einstein, who recognizes that this whole idea of quantum physics turns classical physics on its head and spins it around. Here all these scientists had developed theories and precise formulas for calculating predictably and consistently the ways in which bodies move. Now there’s this idea that little particles actually behave in ways we can’t predict with certainty. These tiny quanta are mysterious. They respond sometimes as particles, and sometimes as waves, and we can’t always tell which way they’re going to go. If a particle is traveling from point A to point B, we can guess its path, but the tinier the particle, the less sure we are that that exact path is the one taken. In fact—hold on to your hat here—we’ve come to understand that not only do we not know the exact path, but that the particles may actually be in two places at once.</p>
<p>Think that’s radical? Back in 1957, a Princeton graduate student named Hugh Everett proposed what is called the “Many Worlds” interpretation. According to his dissertation, quantum theory (the variable behavior of atoms) is true not just for atoms but for everything—like tables, flower pots, SUVs, and even people. Everett was actually stating that these big things could, like tiny pieces of atoms, be in many places at once.</p>

<p>It gets wilder. Everett hypothesized that if you observe a sports utility vehicle (SUV) which is in two places at once, your mind will also end up in two states at once—one which perceives that SUV in one place, and another which perceives it in another place! So, really, there would be two versions of you and each one would perceive a world in which there is a different version of the SUV. Not only that, but these two selves and these two SUVs don’t exist in a vacuum. They actually interact with each other!</p>
<p>This whole concept of multiple realities was a big boon for science fiction writers. The truth is that these ideas are generally considered plausible but not in relation to the large-scale world. We don’t have a way of manifesting alternate universes full of multiple SUVs (thankfully) so we can’t really test it.</p>
<p>But there is one area of the Big World (that which we can see without microscopes) that will be completely revolutionized by quantum theory, and that’s the development of quantum computers. In quantum computers, experimenters are taking advantage of the ability of particles such as atoms to be in many places at once to do many calculations simultaneously.</p>
<p>Talk about high-speed connections. Quantum computers could solve in seconds problems that would take conventional computers millions of years to decipher.</p>
<p>We’re talking WAY beyond quickly downloading your email, obviously. What does this mean for the world? What will these quantum computers do? The staggering truth is that a quantum computer will actually perform in different realities—it will be engaging huge numbers of versions of other computers in alternate universes.</p>
<p>Freaky, huh? But real, and coming soon—or at least, eventually.</p>
<p>Next time you find yourself daydreaming about how your life could be different, ramp it up a notch. Think about quantum physics and the Many Worlds theory. Consider that your life might already be different in some other reality! If it’s possible that it exists exactly as you dream it, there’s no reason you can’t create it here. And heck, you only have to do it in one universe. Piece of cake!</p>
<p>Make that multiple pieces.</p>

<p>Taking the Quantum Leap</p>
<p>While it may seem that the evolution of computers is about at its end, that is not the case. The next generation of computers are quantum computers.</p>
<p>The reason behind continuing computer evolution is the continuing thirst we have for speed and capacity of our computers. Way back in 1947 an engineer and computing expert, Howard Aiken, predicted that all the United States need to satisfy its need for computers were six digital electronic computers. Other scientists and engineers that followed Aiken added to the volume they predicted as being adequately massive, but were also far too conservative.</p>

<p>What none were able to predict that scientific research would produce voluminous quantities of knowledge that needed to be computed and stored, nor did they predict the popularity of personal computers, and the existence of the Internet. In fact, it’s hard to predict if humankind will ever be satisfied with its computer power and volume.</p>
<p><span id="more-33"></span></p>
<p>A basic computer premise, called Moore’s Law, says that the number of a microprocessor’s transistors doubles every 18 months and will continue to do so. What this means is that by no later than 2030 the number of microprocessor circuits found in computers will be astronomically high. This will lead to the creation of quantum computers, whose design will use the power of molecules and atoms for processing and memory tasks. Quantum computers should be able to perform specific calculations billions of times more quickly than can the current computers that are based on silicon.</p>
<p>Quantum computers do exist today, though few and they’re all in the hands of scientists and scientific organizations. They are not for practical and common use – that is still many years away. The theory of quantum computers was developed in 1981 by Paul Benioff, a physicist with the Argonne National Laboratory. Benioff theorized going beyond the Turing Theory to a Turing machine with quantum capabilities.</p>

<p>Alan Turing created the Turing machine around 1935. This machine was made up of a tape whose length was unlimited and which he divided into small squares. Each square either held the symbol one or the symbol zero, or no symbol at all. He then created a reading-writing device that could read these zero and one symbols, which in turn gave these machines – the early computers – the instructions that initiated specific programs.</p>
<p>Benioff took this to the quantum level, saying that the reading-writing head and the tape would both exist in a quantum state. What this would mean is that those tape symbols one or zero could exist in a superposition that could be one and zero at the same time, or somewhere in between. Because of this the quantum Turing machine, in contrast to the standard Turing machine, could perform several calculations at once.</p>
<p>The standard Turing machine concept is what runs today’s silicon-based computers. In contrast, quantum computers encode computer information as quantum bits, called qubits. These qubits actually represent atoms that work together to act as a processor and as the computer’s memory. This ability to run multiple computations at one, and to contain several states at the same time, is what gives quantum computers the potential to be millions of times as powerful as today’s best supercomputers.</p>
<p>Quantum computers that have 30 qubits would, for example, have processing power equal to today’s computers that run at a speed of 10 teraflops (trillions of operations per second.) To put this in perspective, the typical computer of today runs at gigaflop speeds (billions of operations per second.</p>
<p>As our cry for more speed and more power from our computers continues, quantum computers are predicted to be a readily available product sometime in the not so distant future.</p>
