A cloud-based concept called quantum computing-as-a-service (QCaaS) allows businesses to access quantum computing power remotely without the need for expensive quantum hardware.

There is increasing interest in the quantum computing-as-a-service (QCaaS) sector. The primary drivers of this expansion are the growing demand from clients for the application of quantum computing to resolve very complicated issues in a wide range of industries, including banking, medicine, energy, and logistics. Classical computers are incapable of handling such situations. Several reasons are driving the adoption. For example, cloud access has become more appealing because to the cost-effectiveness of accessing the cloud rather than owning quantum gear. Additionally, worldwide funding in quantum research have been steadily increasing.
