The Quantum Scientific Computing Open User Testbed (QSCOUT)

While remote access to quantum computers is increasingly available, in many of these cases the necessary tools to fully specify and characterize the behavior of the hardware itself remains inaccessible. The Quantum Scientific Computing Open User Testbed (QSCOUT) is a ytterbium-ion based system designed and operated with the objectives of full transparency and low-level control to address the potential of near term quantum hardware. QSCOUT's user-accessible software stack includes custom assembly and waveform generation languages. This enables users to both fully specify the native operations and run novel quantum gates via custom pulse sequences. Further, users interact directly with the Sandia scientists who operate the machine, allowing them to realize the full potential and flexibility of the device. This poster highlights current experiment capabilities (including high-fidelity individual addressing and fully parameterized two-qubit gates), selected user results, and plans for future directions and collaboration opportunities with QSCOUT.
