India joins quantum computing race

  • Keen to tap into the next big advance in computing technology, the Department of Science and Technology (DST) is planning to fund a project to develop quantum computers.
  • A quantum computer, still largely a theoretical entity, employs the principles of quantum mechanics to store information in ‘qubits’ instead of the typical ‘bits’ of 1 and 0.
  • Qubits work faster because of the way such circuits are designed, and their promise is that they can do intensive number-crunching tasks much more efficiently than the fastest comparable computers.
  • For instance, to sort a billion numbers, a quantum computer would require 3.5 million fewer steps than a traditional machine, and would find the solution in only 31,623 steps, says a Morgan Stanley analysis last August.
  • Solving other problems, many having to do with computing physics, becomes possible on quantum machines, the authors say, whereas they might never be possible on traditional computers.
