We are now accepting applications for the 2026 Gil Herrera Fellowship in Quantum Information Science. This is a prestigious postdoctoral research and academic fellowship with funding from Sandia's Laboratory Directed Research and Development program. Selected fellows will also be able to take part in our strong academic partnerships between Sandia and our partner universities, which include the University of New Mexico (UNM), UC Berkeley, UCLA, University of Illinois, Purdue, GA Tech, UT Austin, and many others. We seek researchers with a background and interest in the broadly defined interdisciplinary area domain of Quantum Information Science (QIS) and related scientific fields, such as physics, mathematics, computer science, and engineering. We are particularly interested in applicants who can conduct self-directed theoretical and/or experimental research and serve as mentors to students in subject areas such as: algorithms and applications; design, fabrication, benchmarking, characterization, and optimization of quantum devices, novel qubit calibration and control schemes, quantum device and noise modeling, experimental design and discovery, and error mitigation techniques for multi-qubit quantum platforms. As a Herrera postdoctoral fellow, you will have opportunities to address complex problems in support of broad-ranging national security areas, collaborate with highly motivated researchers and faculty in partner universities on challenging research questions using state-of-the-art computational resources, collaborate with Sandia physicists developing multi-qubit systems on a variety of physical platforms (trapped ions, solid-state, superconducting, photonic), present your work at leading publication and conference venues, and share your knowledge with students at our partner institutions, reaching across cultural and institutional barriers. As a Herrera QIS fellow, you will pursue a combination of both self-directed research in your topic area and integration with existing Sandia R&D projects, under the guidance of Sandia staff mentors. A proposal for your research plan will be requested as part of the interview process, and you will be expected to publish the results of your work in leading journals and present your work at top-tier conferences. While hybrid work-modes are possible (such as different work-from-home arrangements) it is strongly desired that the selected fellow relocates to be within reasonable commuting distance from one of the two main Sandia campus locations in Albuquerque (New Mexico) or Livermore (California), prioritizing the home location of their Sandia staff mentor. The selected Fellow will receive a two-year appointment, which includes a highly competitive salary, moving expenses, and a generous professional travel allowance. All interviews will be conducted virtually with an option for selected fellows to visit their physical campus as part of the interview process prior to accepting an offer.
