A qubit -- short for "quantum bit" -- is probabilistic binary in the world of [[quantum mechanics]].
While a bit in computing is either 0 or 1, a qubit (or quantum bit) is the analog of a bit for quantum computation. Unlike an ordinary bit, which may only assume two possible values (usually called 0 and 1), a qubit takes on a range of values between 0 and 1, each having different probabilities. [[Complex numbers]] are typically used to express this continuum of possible values.
