QUANTUM COMPUTER
Do you like this story?
A quantum computer is one which exploits quantum-mechanical interactions in order to function; this behavior, found in nature, possesses incredible potential to manipulate data in ways unattainable by machines today. The harnessing and organization of this power, however, poses no small difficulty to those who quest after it.
Subsequently, the concept of quantum computing, birthed in the early 80's by physicist Richard Feynman, has existed largely in the realm of theory. Miraculous algorithms which potentially would take a billionth of the time required for classical computers to perform certain mathematical feats, and are implementable only on quantum computers, as such have not yet been realized. A two-bit quantum system, recently developed by a coalition of researchers, constitutes the sole concrete manifestation of the idea.
In a quantum computer, the fundamental unit of information (called a quantum bit or qubit), is not binary but rather more quaternary in nature. This qubit property arises as a direct consequence of its adherence to the laws of quantum mechanics which differ radically from the laws of classical physics. A qubit can exist not only in a state corresponding to the logical state 0 or 1 as in a classical bit, but also in states corresponding to a blend orsuperposition of these classical states. In other words, a qubit can exist as a zero, a one, or simultaneously as both 0 and 1, with a numerical coefficient representing the probability for each state.
