The Quantum Computer, Google's New Technology by stingbreed(m): 8:27pm On Sep 07, 2014
You may have seen headlines that Google is working on a quantum computer chip with researchers from the University of California Santa Barbara. But there are some questions you might have before we get into the specifics of the initiative. What is a quantum computer? What can it do? Further, what is Google planning to do with a quantum computer once it’s built one?

Let’s start at the beginning: what is a quantum computer? The University of Waterloo’s Institute for Quantum Computing says that quantum computing is “essentially harnessing and exploiting the amazing laws of quantum mechanics to process information.” Quantum mechanics, in turn, encompasses the mechanics of the motion and interaction of subatomic particles.

A quantum computer is different from a traditional computer in the way that it processes information. A traditional computer uses strings of “bits,” which encode information in zeroes and ones. A quantum computer uses qubits, or quantum bits, units of a quantum system that encodes the zeroes and ones into two distinguishable quantum states. A qubit can represent a zero, a one, or both values simultaneously. But because qubits behave “quantumly,” it’s subject to quantum effects like superposition and entanglement.

Superposition is the ability of a quantum system to be in multiple states at the same time, so that it can be “here” and “there” or “up” and “down” simultaneously. Entanglement is a correlation between quantum particles so strong that it remains perfectly correlated even across great distances, and are said to “dance” in perfect unison even when placed at opposite ends of the universe. Thanks to these effects, a quantum computer can process a large number of calculations simultaneously, and at extremely high speeds.

“Think of it this way,” the University of Waterloo’s page explains. “Whereas a classical computer works with ones and zeros, a quantum computer will have the advantage of using ones, zeros, and ‘superpositions’ of ones and zeros. Certain difficult tasks that have long been thought impossible (or ‘intractable’) for classical computers will be achieved quickly and efficiently by a quantum computer.”

To simplify it a traditional computer processing form exist in either zeros or ones but a quantum computer exist in dual state at the same time. The last time i checked it was the cia that was building one, so even google is planning one.
