A quantum computer is a proposed team that could exploit the quantum mechanical nature of particles such as electrons or nuclei, to manipulate information and use phenomena quantum mechanics to overcome the limitations of time classical complexity. In a standard equipment of today, data is stored in microscopic groves in a hard disk and work through the manipulation of bits that can exist in one of two States (0 and 1), or leave blank. A device, then reads these symbols and blank spaces and gives the machine instructions to perform a particular action. This technology is notable, but science has found a better and more efficient way to perform these actions, and do so in quantum computers. In quantum computers, the data are represented by the quantum properties of one or a single molecule or set of molecules and the data is stored in something called binary digits of quantum or "qubits". Qubits represent atoms, ions, photons or electrons and their control devices respective are working together to act as a processor and memory.
A quantum computer makes hitting the molecule containing information with short pulses of radiation. Quantum computers are not limited to the two States of 1 and 0 as a "classic" or standard equipment. Quantum computers encode information that can exist in a 1, 0 or something intermediate called an overlay. This gives almost unlimited possibilities of quantum team and in theory may be millions of times more powerful than even our main line super teams.
Quantum computers can calculate, encode and decode the information much faster than today's computers. Therefore, Governments around the world are looking for the quantum computer for security technology. With a quantum computer no information would not be safe, the quantum computer could decipher in seconds. But if a quantum computer is used to encrypt the information, any team would today be able to read it. Why everyone people observe closely the advances in this technology and are eager to get their hands first. Unfortunately for them, quantum computers are still far away. At least this technology is 10 or 20 years away from being practical. 2008 Quantum computers have only been able to run in 16 qubits. This equipment was made by a Canadian company called D-Wave and was able to solve a complex Sudoku. This is a great step in making a practical quantum computer and if computer technology is moving at its current pace we we can see them in our homes, schools and businesses before we think.
