But there is an even more radical possibility. Computers today store information as bits that are made up of 0s and 1s. But 15 years ago scientists realised that there was a new way of storing information; a 'qubit'.
A qubit can be a 0 and 1 at the same time. Qubits would form the basis of a quantum computer.
