Visions 2: Quantum information
All computers used today follow a classical physics approach.
That is, a ‘bit’ of information is stored in a physical system (as a voltage, magnetic spin or light pulse) which can take two sharp values, 0 and 1.
However, by harnessing quantum properties, which are quite different from classical ones, totally new types of computing processes could be developed.
