    Big Picture Science discusses the breakthroughs around the detection of cosmic neutrinos with Kate Shaw, experimental particle physicist at the University of Sussex who works on DUNE.

    SQMS Study Links Qubit Performance to Material and Fabrication Features

      Researchers from the Fermilab-led SQMS Center identified material and fabrication features associated with variations in superconducting qubit performance. It is one of the most comprehensive studies ever conducted, linking materials and their structures to variations in quantum device performance.

      New DOE Early Career project uses magnetic vortices to uncover hidden sources of loss in superconducting quantum devices

      Daniel Bafia will develop a new measurement approach that uses magnetic vortices to investigate defects and interfaces that can limit the performance of superconducting quantum devices. The project could provide researchers with a new way to understand and ultimately reduce sources of energy loss in quantum materials.

      Fermilab physicist wins DOE Early Career Award to study dark matter with entangled qubits

      Building on her earlier work with quantum amplifiers for a leading dark matter experiment, Rakshya Khatiwada will use a four-qubit entangled system to test whether it offers a sensing advantage when exposed to a simulated dark matter signal. The project, based at Fermilab, could open the door to detecting dark matter candidates such as axions and dark photons.
