Quantum computers use quantum physics to build extremely powerful computers. When these are linked to the cloud, it becomes quantum cloud computing. IBM, AWS, and Azure all provide a quantum computing service to select customers. The increased power of quantum computers and the use of the cloud may make AI and ML more powerful and will allow modeling of complex systems available on a scale never seen before. Quantum cloud computing has the ability to transform medical research, AI, and communication technologies.

A concern for quantum computing is that traditional methods for encryption/decryption could become obsolete as the vast power of the cloud coupled with quantum computing makes the search space more manageable. This would effectively break current cryptographic methods. New quantum methods of encryption would be necessary or methods not susceptible to quantum computing.
