Today’s computers store information as bits, where each bit holds either a “1″ or a “0.” But a quantum computer is built around quantum bits, or qubits, that can store a 1, a 0 or any combination of both 1 and 0 at the same time. For example, a qubit could be 90 percent “0″ and 10 percent “1.”
So far, all we’ve seen are some proofs of concept that can do simple calculations, but a full-blown quantum computer consisting of many qubits would be able to perform complex calculations far outside the limits of even the most powerful of today’s supercomputers.
