Enabling Low Level Hardware Access with the Quantum Scientific Computing Open User Testbed (QSCOUT)

ORAL

Abstract

The Quantum Scientific Computing Open User Testbed (QSCOUT) is a quantum processor based on Yb-171 trapped ions operated and housed by Sandia National Laboratories. Distinct from most commercial platforms, QSCOUT offers users transparent pulse-level control, enabling customized gate operations and allowing flexible qubit manipulation. Our custom-developed Jaqal (Just Another Quantum Assembly Language) includes full parameterization of single qubit rotation gates, two-qubit Mølmer-Sørensen (MS) gates, and the ability to define pulse waveforms. Here, we discuss how we employ both the QSCOUT hardware and the Jaqal software to offer users unique low-level access to the experiment for their quantum computing applications. We present current capabilities offered on the system through a survey of current users as well as future integrations, developments, and collaboration opportunities.
