The Superconducting Quantum Materials and Systems Center (SQMS) and the Computational Science and AI Directorate (CSAID) at Fermi National Accelerator Laboratory and Rigetti Computing have teamed up to define and deliver a standard pathway for quantum computing at Rigetti from HEPCloud. HEPCloud now provides common infrastructure and interfacing for managing connectivity and providing access to remote quantum resources using cloud services. HEPCloud provides the tools necessary for scheduling and running quantum applications that not only require QPU resources, but also a tight coupling with classical algorithms that utilize use QPU resources as co-processors. With this new interface, quantum resources can be accessed through familiar job submission and monitoring grid infrastructure available at the Fermilab computing facilities. The system incorporates AWS to handle both the application computational load and the communication link to Rigetti QPUs. The AWS resources can also be readily used for simulators and testing before actually submission through to Rigetti.

We have demonstrated applications ranging from optimization with QAOA, to experiments measuring qubit fidelity, to qutrit problems using the pulse package Quil-T. Notebooks developed for interactive use can readily be used with straightforward modifications to command line processing. Our computing model includes moving data into and out of AWS and Rigetti. Here we describe use cases driving this development, working example applications, the overall system architecture, and the facilities that are currently used.
