A university of Utah physicist Christoph Boehme and colleagues took a step forward developing a superfast computer based on the wired reality of quantum physics by showing it is feasible to read data stored in the form of the magnetic spins of phosphorus atoms.
In a computer with three bits,there are eight possible combinations of 1or 0 .But three bits in a digital computer can store only one of those combinations at a time. Quantam computers would be based on the strange principles of quantam mechanics-the smallest particle of light and matter can be in different places at the same time.In a quantam computer, one quantam bit-could be both 0 or 1 at the same time.So with three quantambits of data, a quantam computer could store all eight bit combinations of 0 and 1 simultaneously.That means a three quantam bit computer could calculate eight times faster than a three-bit digital computer.
Personal computers today calculate 64bits of data at a time. A quantam computer with 64qubits would be 2 to the 64th power faster,or about 18 billion times faster.
