This is a multi-disciplinary field that runs across physics and maths to engineering and computer science. Quantum computing exploits sub-atomic Qubits that store and process information surpassing the traditional computers. It is done at a scale and speed that cannot be matched by a supercomputer.

Governments have committed billions of dollars to quantum computing initiatives. Even private investors have been lured by this field.

Quantum computing must have mechanisms to ensure human accountability with respect to its design, uses and outcomes.

Quantum computing has applications in various industries, say quality of batteries, simulation of chemical reactions, pharmaceutical drug discovery, tracking of digital transactions.

There will be greater risks to cyber security in quantum computing.

Nations must invest in nurturing talents in quantum science. World powers are not just militarily superior and economically strong. They must also have technological abilities.
