Sandia's Quantum Scientific Computing Open User Testbed (QSCOUT)*

Trapped ions are a leading candidate for quantum computation due to their high-fidelity gate operations, indistinguishability, qubit connectivity, and routes to scalability. Harnessing these advantages, we are developing the Quantum Scientific Computing Open User Testbed (QSCOUT) based on a trapped-ion quantum register at Sandia, using our microfabricated surface electrode traps to host chains of ions with all-to-all connectivity adaptable to diverse algorithms. Here, we present the experimental development of QSCOUT, the current and anticipated capabilities of the testbed, as well as opportunities for use of this platform. As an open testbed, it will feature fully specified operations and hardware allowing users to modify quantum gates and pulse sequences for desired control.
