thumb|upright=0.6|The general definition of a qubit as the quantum state of a two-Energy level|level quantum system In quantum computing, a qubit () or quantum bit is a basic unit of quantum information; a binary qudit the quantum version of the classic binary bit physically realized with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics. Examples include the spin of the electron in which the two levels can be taken as spin up and spin down; or the polarization of a single pho
