...every 2 years, however due to physical restrictions it is believed that this number will stop growing in a few decades. Scientists already have to deal with problems which classical computers are unable to solve, for example, simulations of atomic quantum systems. For this very reason researchers all around the world started to put their efforts into creating a fully functional quantum computer. HOW DO QUANTUM COMPUTERS WORK? As you might know, classical computers operate in bits, which can have one of the two values at the time: either 1 or 0. However, quantum computers operate in quantum bits or qubits, which are usually represented by such particles like atoms, ions, electrons, and photons. All of these particles have a property called superposition, which means that they can be of two states at the same time, that is a qubit can represent both 1 and 0 at the same time. To put it simply we can illustrate superposition with a famous physicist’s Erwin Schrodinger’s thought experiment: if we put a living cat in a closed box rigged with a device that can randomly release poison (there is equal probability that it will release and won’t) we can say that until we open the box to check the state of the cat, it’s both dead and alive at the same time. And that’s the whole reason why quantum computers are superior to classical ones. For example, a 3 bit register can save only one of the 8 (23) possible bit combinations at the time, but a quantum register of the same size could save...

...Computer-delivered electronic system that allows the user to control, combine, and manipulate different types of media, such as text, audio, video, graphic and animation. The most common multimedia machine consists of a personal computer with a sound card, modem, digital speaker unit, and CD-ROM. Long time as the future revolution in computing, multimedia applications were, until the mid-90s, uncommon due to the expensive hardware required. With increases in performance and decreases in price, however, multimedia is now commonplace. Nearly all PCs are capable of displaying video, though the resolution available depends on the power of the computer's video adapter and CPU. One of the multimedia elements is audio. Audio include music, speech ,or any other sound. Audio and digital music are different from other multimedia elements. This is because the audio and digital music is not related to visual .Audio cannot be seen but can only be heard with the ears only. Computer will result in vibration of air through the speakers or sound box, while our ears detect vibrations in the air. As the sound wave moves away from the vibrating object, the individual molecules do not advance with the wave, they vibrate at what is termed their average resting place until their motion still or they are set in motion are the component that make up a sound wave, frequency, amplitude, velocity, wavelenght, and phrase. Before the continuous wave analog audio can be stored in a computer...

...D-Wave Computer's Solution Raises More Questions Sophie Bushwick An experimental computer made by a Canadian company has proved its ability to solve increasingly complex mathematical problems. But the question remains — just how much of this calculating power is actually due to the strange properties of quantum mechanics? In theory, quantum computers can perform calculations far faster than their classical counterparts to solve incredibly complex problems. They do this by storing information in quantum bits, or qubits. At any given moment, each of a classical computer's bits can only be in an “on” or an “off” state. They exist inside conventional electronic circuits, which follow the 19th-century rules of classical physics. A qubit, on the other hand, can be created with an electron, or inside a superconducting loop. Obeying the counterintuitive logic of quantum mechanics, a qubit can act as if it’s “on” and “off” simultaneously. It can also become tightly linked to the state of its fellow qubits, a situation called entanglement. These are two of the unusual properties that enable quantum computers to test multiple solutions at the same time. But in practice, a physical quantum computer is incredibly difficult to run. Entanglement is delicate, and very easily disrupted by outside influences. Add more qubits to increase the device's calculating power, and it becomes more difficult to maintain entanglement. Instead of struggling to keep ever-larger numbers of qubits...

...Quantum Computers & Quantum Cryptography Innovations in IT Mayi UmBayemake Health Informatics 500 May 17, 2015 Abstract This research pertains to Quantum Computers and Cryptography. These topics have emerged greatly in the past few years, are proven to be very important and useful to businesses. The use of quantum computers and cryptography will be able to offer faster processing of information and security. Quantum computers are being developed with qubits to hold an exponential amount of data. This could be proven a necessity for any business or organization. Quantum Cryptography is the ability to encode data on a computer making it difficult for it to be decoded. This causes the data to be nearly impossible for copying. In this paper I will discuss how this emerging technology will benefit my organization. Introduction The topic of technology is an ever revolving topic that changes happen daily. From phones, to computers, vehicles and anything that you can think of, technology has made its impact. Computers have been the fastest evolving technology for decades. Computers have changed so much that people have given up on learning all of the updated emergences. Quantum technology has been in the making for years now. This system is supposed to offer a faster and discrete way to process information. Albert Einstein and his associates did not believe in the viability of Quantum mechanics and felt that its “power” will never be harnessed. They presented many theories...

...available to the world is a triumph mainly attributable to breakthroughs such as those given by Tim Berners-Lee with his introduction of the World Wide Web in the early 1990’s, and constant developments in computer science and computational power made possible through advances in microprocessing capabilities which seem to be paralleling closely with forecasts given by Moore’s Law (Greenemeir, 2009). Moore’s Law, which is not exactly a law, is an estimation regarding the progression deemed possible in an integrated circuit. It was postulated by one of the founders of Intel, Dr. Gordon Moore, who stated that the number of transistors placed on a circuit will double roughly every 18 months (Colwell, 2013), and the capacity to follow this trend will end at a critical point when transistors become so close together that the manifestations of quantum mechanics will begin to transpire (Tally, 2012). Classical computers have undoubtedly reshaped our world and have provided incalculable progress unforeseen through the eyes of some of history’s greatest academics. Early computers were mammoth-sized mechanical devices utilized by the military for processing information that would take humans hours by manual calculation alone (Watson, 2012). Computers, in the days prior to digital computers, were actual people who would literally compute information for whatever their task or job may have been. Though these positions were often filled with clever mathematicians, their capacity to compute problems...

...INFORMATION TECHNOLOGY IN ELECTRICAL ENGINEERING Electrical engineering is one of the newer branches of engineering, and dates back to the late 19th century. It is the branch of engineering that deals with the technology of electricity. Electrical engineers work on a wide range of components, devices and systems, from tiny microchips to huge power station generators. Electrical engineering has now subdivided into a wide range of subfields including electronics, digital computers, power engineering, telecommunications, control systems, radio-frequency engineering, signal processing, instrumentation, and microelectronics. Early experiments with electricity included primitive batteries and static charges. It has been a subject of scientific interest since at least the early 17th century. The first electrical engineer was probably William Gilbert who designed the versorium: a device that detected the presence of statically charged objects. He was also the first to draw a clear distinction between magnetism and static electricity and is credited with establishing the term electricity. In 1775 Alessandro Volta's scientific experimentations devised the electrophorus, a device that produced a static electric charge, and by 1800 Volta developed the voltaic pile, a forerunner of the electric battery. However, the actual design, construction and manufacturing of useful devices and systems began with the implementation of Michael Faraday’s Law of Induction, which essentially states that...

...OF PURPOSE One sunny morning in 2005 while reading the newspaper, suddenly an article captured my attention. It was the Stanford Commencement Speech of Steve Job. The narration of Steve job’s life in three stories inspired me so much that I wanted to learn building user-friendly computers and work in the Silicon Valley. Eventually, when I was taught about computer operations in my school, I had an intuitive feeling that I wanted to be a computer scientist. Consequently, the hunch and evasiveness led me to study Computer Science and Engineering. In my junior year, I found out the field of the computer that interests me the most- computer security. While studying the Computer Networks course, I lost counts of hours studying different...

...area network. These networks rely on electromagnetic airwaves to transmit and receive over a defined area, usually a few hundred feet. (Yahoo-wireless) In most cases, a wireless transmitter will be connected directly to a wired land network using Ethernet cables. Once the network feed has been connected to the transmitter, and a constant power supply is established, a steady stream of radio, or infrared waves with be produced (both are electromagnetic waves). The vast majority of wireless LAN systems tend to rely on radio waves as the carries for their signals, because infrared waves tend to have a shorter distance at which they are able to transmit, and are more easily interrupted. Radio waves, or radio carriers as they are referred to, transfer data through modulations of the carrier signal. The addition of data to a radio carrier causes the signal to occupy more than a single frequency. Once data is imprinted onto the radio signal it is a simple reversal of the transmitting process that allows the information to be decoded by a receiving station. (Rho Wireless) Radio waves offer another benefit to the wireless system in addition to their range. With radio signals it is possible for multiple carriers to exist in the same space at the same time without interfering with each other. The key to making this possible is variation of frequencies....

...before. One small example of such innovative technology used in today’s health care industry is the Cardiac Ultrasound Machine. Our understanding of physics has helped in better diagnosing problems without having to perform invasive procedures like before. The world of imaging in medical sciences and treatment has benefitted the most from this understanding. In today’s health care, sound waves such as the ultrasounds have changed diagnostic procedures for ever. This fact is exemplified in the invention of Cardiac Ultrasound Machine. The machine mainly consists of a transducer probe, central processing unit, transducer pulse controls, display and keyboard, storage device and a printer. The functionality of the machine depends on the piezoelectric crystals and their ability to generate sound with the absorbance of electricity. The alternating voltage causes the piezoelectric crystals to become polarized and vibrate to produce sound. Materials with piezoelectric properties such as lead titanate (PbTiO3) and lead zirconate (PbZrO3) treated by poling will generate and detect ultrasound waves when subjected to alternating electric fields or mechanical stresses. The probe transmits high frequency...

...ideas invented radar together yet separately. One thing we do know is that Scottish physicist James Clerk Maxwell composed the Electromagnetic Field theory, which states the shape and speed of electromagnetic waves. James Clerk Maxwell developed this theory in 1865; his ideas would be expanded on by other inventor and thinkers to come, including Guglielmo Marconi in 1897, who is now thought of as a pioneer of radio communication. Radar technology didn’t really become a viable field of study until around the Second World War, when the threat imposed by Germany grew into a race to defend allied countries and their borders. The first country to use radar in a defensive capacity was Great Britain, by the start of the war they had 19 stations that used radar to detect enemy aircraft, and by the wars end there were 50 stations setup....

...Shah Basit Hussain Qureshi Istanbul, Turkey Wireless technology Explained with examples as below: Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or the entire communication path. Some monitoring devices, such as intrusion alarms, employ acoustic waves at frequencies above the range of human hearing; these are also sometimes classified as wireless. The wireless method of communication uses low-powered radio waves to transmit data between devices. High powered transmission sources usually require government licenses to broadcast on a specific wavelength. This platform has historically carried voice and has grown into a large industry, carrying many thousands of broadcasts around the world. Radio waves are now increasingly being used by unregulated computer users. Humans communicate in order to share knowledge and experiences. Common forms of human communication include sign language, speaking, writing, gestures, and broadcasting. Communication can be interactive, transitive, intentional, or unintentional; it can also be verbal or nonverbal. In addition, communication can be intrapersonal or interpersonal. The first wireless transmitters went on the air in the early 20th century using radiotelegraphy (Morse code). Later, as modulation made it possible to transmit voices and music via wireless, the medium came to be called "radio." With the advent of television, fax, data communication...
