Quantum Computing: A glimpse

Today’s computing is limited to having a single value of either 0 or 1 for each bit, quantum computing uses quantum bits (qubits) that are simultaneously in both states (0 and 1) at the same time. This phenomenon is called as the SUPERPOSITION. The consequence of this superposition is that quantum computers are able to test every solution to a problem at once. Further, because of this exponential relationship, such computers should be able to double their quantum computing power with each additional qubit.
