Quantum computing is a few years away from powering real commercial applications. Organisations are optimistic about its potential and have launched proof of concepts (PoCs). The interest in the technology has increased and there are breakthroughs in technologies. There are improvements in quantum hardware, algorithms and techniques to accelerate the conventional technology models.

Quantum computers solve the problems previously thought intractable by manipulating particle physics of atoms, photons and electrons. There is exponential speed-up as compared to the best supercomputers. The communication becomes secure. The measurements are too fast and too precise. The collectivity of these is called quantum advantage which you score over classical systems in use now.

Capgemini, a French IT company, has set up Q-Lab in India to harness the potential of quantum technologies. It aims to become a leading quantum integrator globally. It is not necessary to wait for the technology to mature before adopting it. Its use must be explored by examining use cases and by finding skill gaps. Organisations have to be quantum-ready, which is a long journey.

A five-step approach is adopted by Capgemini to invest in quantum technology. One must harness the quantum advantage as soon as it appears. There should be assessment for quantum investment. A small team of experts must be constituted. The team translates the potential use cases to small quantum experiments to avail of the quantum advantage. Long-term partnerships must be made with technology providers. And in-house skills must be developed.

The areas of quantum applications could be aerospace, energy, chemicals and medicines and life sciences.
