Quantum-as-a-Service (QaaS)
Quantum-as-a-Service (QaaS) - also called Quantum Computing as a Service (QCaaS) - is essentially cloud-based access to quantum computing resources. In simple terms, a third-party hosts quantum computers (and related software tools) in the cloud, and users access those quantum capabilities remotely over the internet. This model parallels other “as-a-Service”…
