Quantum Performance Lab

Sandia Quantum Performance Laboratory



Who we are and what we do

The Quantum Performance Laboratory is an R&D group within Sandia National Labs.  We develop and deploy cutting-edge techniques for assessing the performance of quantum computing hardware, serving the needs of the U.S. government, industry, and academia.  Our research produces

  • insight into the failure mechanisms of real-world quantum computing processors
  • well-motivated metrics of low- and high-level performance, 
  • predictive models of multi-qubit quantum processors, and 
  • concrete, tested protocols for evaluating as-built experimental processors.

We maintain and support the open source pyGSTi software package, which provides an extensive suite of cutting edge tools and algorithms for evaluating individual qubits and many-qubit processors.  PyGSTi is the reference implementation for gate set tomography (GST), and also integrates implementations of many other protocols for characterizing noise and errors in qubits, and quantifying their performance.  

We collaborate with a wide range of partners in industry and academia to develop new performance assessment tools and apply them to newly developed quantum computing platforms, and we publish our research results in scientific journals including Nature CommunicationsPhysical Review X, and Physical Review Letters.  In addition to our R&D capabilities, the QPL also provides quantum hardware assessment capabilities directly to DOE and the U.S. Government.

QPL Announcements

The Assessing Performance of Quantum Computers (APQC) workshop (Sep. 25-27, 2019 in Estes Park, CO) will bring together experts in QCVV, hardware, error correction, and algorithms to measure the performance and power of cutting-edge quantum computational hardware. APQC is organized by the QPL and the University of New Mexico's CQuIC, with support from the National Science Foundation.  Click here for additional information, and here for application, registration, and abstract submission.
