Unlike the classical bits of data in a computer, which are decidedly either a zero or a one, qubits hover in an indecisive fog somewhere between these two values.
These gates manipulate qubits, which,
unlike classical bits, can represent both a 0 and 1 at the same time, making it theoretically possible to compute the answers to large problems much faster than on an ordinary computer.
Not exact matches
Unlike a digital
bit in a
classical computer, which can take the form of either 0 or 1, a qubit can be both zero and one simultaneously, throwing open the door to vastly more powerful computation.
Unlike classical computers, where the basic unit of information, the
bit, is either 0 or 1, qubits can be 0, 1, or any mathematical superposition of both, allowing for more complex operations.
Unlike classical computer
bits, which utilize a binary system of two possible states (e.g., zero / one), a qubit can also use a superposition of both states (zero and one) as a single state.
