Qubit
A quantum bit or qubit (pronounced /ˈkjuːbɪt/) is a unit of quantum information. It is the quantum analogue of the classical bit. It is described by a state vector in a two-level quantum-mechanical system, which is formally equivalent to a two-dimensional vector space over the complex numbers.
