Trends in Computer Architecture
Since the introduction of the first computer, the search for computer architecture that is faster, smaller, and more efficient has been a constant goal of the computer industry. The first computers were large, heavy machines composed of thousands of vacuum tubes. The development of the transistor created the next evolution in computer architecture, the microchip. This is the architecture used in the current generation of computers. Like its vacuum tube predecessor, this architecture of utilizing transistors, can only go so far. Moore’s Law predicts that the number of components on a chip doubles every 18-24 months. At this rate each switch will eventually become the size of an atom. When this happens the laws of quantum mechanics must be used. A new evolution in computer architecture will need to be developed to handle the unique laws of quantum mechanics. This architecture is already being developed and is called a quantum computer.
Quantum computers work in a rather distinctive way. Instead of using traditional bits, they use quantum bits, or qubits. These qubits are particles that can take on the unique states required for quantum computing. The best way to understand how a quantum computer works is by example. A basic example is to take a register composed of 2 bits. Using a classic register, these two bits can have a value of 0,1,2, or 3. Now using a quantum register with two qubits, the register can have a value of 0, 1, 2 and 3 all at ...
Living as royalty in Hungary and dividing eight-digit numbers in his head before age six, it was only a matter of time before John Von Neumann would go on to create some of the world’s most important economic theories and mathematical models (Poundstone, 1992; Burks, 1966). Neumann not only founded the study of game theory, but was also the first man to create a self-replicating machine without the use of a computer (Burks). These achievements also led to his principal membership in the Manhattan Project, one of the most globally influential scientific initiatives (Regis, 1992). John Von Neumann’s story is one of intense intellectual curiosity, and his achievements are nothing short of fascinating.

Chapter 1 Quantum Neural Network 1.1 Introduction and Background The eld of arti cial neural networks (ANNs) draws its inspiration from the working of human brain and the way brain processes information. An ANN is a directed graph with highly interconnected nodes called neurons. Each edge of the graph has a weight associated with it to model the synaptic eciency. The training process involves updating the weights of the network in such a way that the network learns to solve the problem.

Moor’s Law: The number of transistors incorporated in a chip will approximately double every 24 months. (Moore, 1965)
... helps me because it explains how we approached quantum computing and how quantum computing can work in diverse ways. Overall, it will help me describe to the reader on what a quantum computer is and how it works.
The Von Neumann bottleneck is a limitation on material or data caused by the standard personal computer architecture. Earlier computers were fed programs and data for processing while they were running. Von Neumann created the idea behind the stored program computer, our current standard model. In the Von Neumann architecture, programs and data are detained or held in memory, the processor and memory are separate consequently data moves between the two. In that configuration, latency or dormancy is unavoidable. In recent years, processor speeds have increased considerably. Memory enhancements, in contrast, have mostly been in size or volume. This enhancement gives it the ability to store more data in less space; instead of focusing on transfer rates. As the speeds have increased, the processors now have spent an increasing amount of time idle, waiting for data to be fetched from the memory. All in all, No matter how fast or powerful a...
Quantum computing is the first step into all technologies of the future. It involves using electric patterns in the brain to control electronics. A twenty-six-year-old quadriplegic has an implant the size of an aspirin sitting on the top of his brain that allows him to play simple video games, control a robotic arm, and even turn on and off a TV. By 2012 cyber kinetic chips could be able to process thoughts as fast as speech (Taylor). The transition eventually will be made from implants to headbands with unimaginable power. With this headband “Any kind of information is available anytime [a user wants]it, simply speak a question or even think it. [Once connected, a person]will always be connected wirelessly to the network, and an answer will return from a vast collectively-prodeuced data matrix. Google queries will seem quaint”(Kirkpatrick). With this breakthrough, the necessity to learn languages may disappear (Kirkpatrick). The biggest step is “network e...
Computers are changing the world as we know it, and they offer an exciting new way of working. The news represented a complete turnaround for the corporate giant. Microsoft Chairperson, Bill Gates publicly announced his company's new connection to the Internet. The announcement rang through the nation. Gates has consistently ignored the Internet in favor of desktop computing. So, with Microsoft's approval, computers kicked into even higher gear . The pace of innovation continues to astonish even those involved from the start. If one wants to find enthusiasm, intellect, hard work, and imagination; then computers is the place to be .
Scientists Catherine C. McGeoch and Cong Wong have been working on the quantum computer. The quantum computer works by not being limited by ones and zeros and can actually read 1.1 as a valid number. Being able to read .1 higher doesn 't seems like a big deal but when these quantum computers are put up against gaming computers the quantum has a faster processor ("Harnessing Energy Sensory Processing"). These studies have been theorized about for years but we just now have the technology to be able to get this revolutionary idea into reality. The theory behind this is that with any extra amount being able to read in the processes that increases the potential of a processor exponentially. At the moment quantum computers cost about 6,000 times more to make than a normal gaming PC. Your average gaming computer goes for about 1,000 dollars and up granted 1000 is low end for gaming computers and it does not leave much room for a really good Intel brand processor. Not only would the idea of quantum computers not have existed without the creativity that comes from technology, but we also would have left standard processors at dual and quad core set ups. Now days any server for a company has at least 8 cores or a 16 core processor. The cores in a standard PC just help the other cores with strain and make the pc able to handle more processes at one
asteroid was on a line with Earth, the computer would show us and enable us
A processor is the chip inside a computer which carries out of the functions of the computer at various speeds. There are many processors on the market today. The two most well known companies that make processors are Intel and AMD. Intel produces the Pentium chip, with the most recent version of the Pentium chip being the Pentium 3. Intel also produces the Celeron processor (Intel processors). AMD produces the Athlon processor and the Duron processor (AMD presents).
My interest in Computers dates back to early days of my high school. The field of CS has always fascinated me. The reason for choosing CS stream was not a hasty decision. My interest started developing in the early stage of my life, when I studied about the invention of computers. The transformation from the large size to small palmtops enticed me to know about the factors responsible for making computers, also the electronic gadgets so small. I was quite impressed after seeing a small chip for the first time in my school days, especially after I learnt that it contained more than 1000 transistors, “integrated circuits”.
... in the field of computing. Because computers operate on a binary system it is possible that individual quanta cold be used to store information. This is possible because quanta can be in two states, horizontal and vertical. Using quantum teleportation information can instantly be sent from one point to another. An example of quantum computing could be if a person had to search a dorm for a specific item. Normally the person would have to go to every door in turn and look inside but if this were a quantum computer doing the searching it could look in every room at the same time.
