An open quantum testbed based on trapped ions (QSCOUT)*

At Sandia National Laboratories, we are developing and operating an open user testbed for quantum information protocols based on trapped ions, known as the Quantum Scientific Computing Open User Testbed, or QSCOUT. This testbed provides not only the opportunity to perform quantum algorithms and study noisy-intermediate-scale quantum (NISQ) systems, but unlike many commercial testbeds, it also allows users control of the system both at the quantum-circuit level and at the more fundamental pulse-control level to study alternate methods of gate construction and optimization.  Here, we present our progress thus far in developing the testbed and running algorithms for our users, as well as some of the experimental and software challenges encountered in developing such a system. We also discuss the current and anticipated capabilities of QSCOUT.  

SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. SAND2021-13359 A
