Paradigm Shifts in Information and Communication Technologies: Towards Quantum Computers

The paper delineates various paradigms and trajectories followed in information and communication technologies since the invention of first mechanical computer in 1822. The authors argue that next generation of computer could be based on quantum, a concept invented by Max Plank, a German Physicist in 1900. Computers in the new paradigm would be based on qubit rather than present day bit structure. This paradigm shift in computational technologies would not only enhance the speed of computers manifold but also allow parallel processing to a great extent. The authors demonstrate how the new technology would revolutionize the application of ICT with unprecedented security of data and information. The cloud computing could be very effective in the new ICT paradigm.
