**(CIO.EconomicTimes.India)** Quantum computing can improve AI systems dramatically, not just because they can work faster than traditional computers, but because they can do things differently. Quantum computing takes advantage of the strange ability of subatomic particles to exist in more than one state at any time. Due to the way the tiniest of particles behave, operations can be done much more quickly and use less energy than classical computers. Quantum computers will be able to complete complex calculations in mere seconds – same calculations that would take today’s computers thousands of years to solve. Regarding Big Data, quantum computing will enable organizations to sample large troves of data and optimize for all types of use cases and portfolio analyses.

Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. The best known example of quantum cryptography is quantum key distribution which offers an information-theoretically secure solution to the key exchange problem.

The global market for quantum computing services and hardware will exceed $6.4 billion USD by 2023.
