Quantum Computation exploits the principles of quantum mechanics, the science that controls the computational process. Nformation may be stored in "Qubits" which may exist in all countries concurrently. A qubit may store "0" and "1" at a time, if one builds two Qubits they may contain four values at a time; 11, 10, 01 and 00. It looks ridiculous to say that everything is both X and non-X. The theory was first suggested in 1985 by the British physicist David Deutschl. A number of elementary particles such as electrons or photons, can be used as a depiction of either 0 and/or 1 in a quantum device, with their charge and polarization. Both these particles are referred to as a quantum bit or qubit.
