Quantum Computing: An upcoming Component innovation
The basic idea is superposition, where a single particle can exist in multiple states simultaneously. Classical Computer works with bits, it can be either 1 or 0 at once. But Quantum computers work with qubits, they can be 1 and 0 at the same time. Now thats just the basic idea of it.
Presently there are some calculations that even the best present computers might take much time to calculate, but quantum computers will speed up computing exponentially.
How Does a Quantum Computer Work?
To understand how this technology works at subatomic level, watch the following links. Its very interesting.
