Rigetti On-Premises Quantum Computing Systems are full-stack superconducting quantum computers that Rigetti designs, builds, and installs at customer facilities. The line spans from nine-qubit units up to the 108-qubit Cepheus-1 system, which reached general availability in April 2026. Each deployment includes the processor, control hardware, and software stack.

Customers include national laboratories, supercomputing centers, and government programs that need dedicated capacity and data control. Examples include the HPE and Pittsburgh Supercomputing Center collaboration and the order from India's Centre for Development of Advanced Computing. Installed systems let operators tune performance on site and integrate quantum resources with classical high-performance computing.
