Quantum Computing – Making A Choice

Much of the 21st century knowledge on consumer electronics and highly advanced technologies is based on man’s growing understanding of Quantum Mechanics. This relatively new development in physics is concerned with the subatomic world, of particles and spheres scientists named with Greek and Latin letters, and of the field’s aim to control, predict and manipulate such worlds that people can never see yet exist. It is opposed to theoretical physics work. Never mind (or at any rate set aside) the current Holy Grail of science, the general unified theory or string theory, because the conflicting, confusing and seemingly dice-playing Quantum Mechanics gives scientists the research and application for the development of information technology, computer science, and many other areas of engineering. At least it has real world application unlike the string theory. And yes, even the current hype on touch-screen devices involves the subatomic worlds.

A little explanation of the Quantum mechanics first. In the Quantum world, everything is a chaos; there is nothing that can be predicted in subatomic level, unlike the physical world. But of course they can be controlled and manipulated for real world application. One such technological application of the die-player Quantum mechanics is the Quantum computer/computing. They are unlike the transistor-based traditional computers.

Some Quantum Computing Ideas

With a Quantum computer, the use of subatomic particles and their phenomena, such as superposition and entanglement, are possible; thus making the ‘dice-playing’ predictable and controllable. Scientists can now perform operations on quantum data; and the basic idea here is that quantum properties can represent data and be operated upon. It is first thought out by physicist Alan Turing in 1936 and theorized the universal quantum computer, also referred to as the quantum Turing machine. It will not be less right to say than instead of traditional bits and bytes, Quantum computers use particles of all the Greek and Latin alphabet.


Quantum computers will have switches that can be in an on or off state simultaneously unlike current PCs. The mechanism that will make this possible is known as superposition. The switches are known as quantum bits. The system will make quantum computers operate very fast. A basic quantum computer is liable to be operational by 2020.

Random Mind Blab About Quantum Computing

However, close to a century hence, quantum computer is still in its infant stages. But it has ceased to be only a matter of theoretical research, and is starting to take shape in applications and experiments. Computations for such experiments are done on quantities of quantum bits (qubits for short). And all the while governments and research facilities are now supporting the development of Quantum computers because of its potential for an ever more powerful, accurate and faster calculations and computations. Military men will obviously like its implications.

In essence, a Quantum computer is a very powerful computer. Its memory can be exponentially larger, such as in millions of terabytes (scientists probably do not have a name yet for it); but only with a minimal size, say a card or a chip. It can calculate millions of inputs simultaneously and even faster and better. It will certainly have great implications on day-to-day living, if Quantum computers are mass-produced in the very near future. And it will not be less right to say that Quantum computing is the future of all present-day computers. However, only time will tell if this highly-advanced technology is too hard to build.
