To cool quantum computing components, researchers use machines called dilution refrigerators. Researchers and engineers from the SQMS Center are building Colossus, the largest, most powerful refrigerator at millikelvin temperatures ever made. The new machine will enable new physics and quantum computing experiments.
SQMS Center researchers have fabricated quantum devices to evaluate the effect of different materials on qubit performance, thanks to proximity to the Pritzker Nanofabrication Facility.
Koch has assumed the leadership role previously held by Jim Sauls, who will remain active at SQMS.
Scientists at the SQMS Center have directly probed silicon’s impact on the lifespan of superconducting qubits. The uniquely sensitive measurement helped researchers quantify how the material impacts qubit performance.
Researchers look toward quantum computing to help medical-imaging scientists achieve the goal of accurately measuring tissue properties with MRI scans.
The Mu2e experiment at Fermilab will look for a never-before-seen subatomic phenomenon that, if observed, would transform our understanding of elementary particles: the direct conversion of a muon into an electron. An international collaboration of over 200 scientists is building the Mu2e precision particle detector that will hunt for new physics beyond the Standard Model.
Scientists at the Fermilab-led SQMS Center investigate qubits at the atomic level to identify sources of various impurities. By having a deeper understanding of how impurities affect how long a qubit can store information, scientists will be able to figure out how to further improve the performance of quantum computers.
For years, scientists have wondered how the observed afterglow of the Big Bang relates to the distribution of galaxies in our universe. Now, thanks to a new map of dark matter, they have direct evidence that a cold region in the afterglow coincides with the lack of matter in the same patch of the sky.
Physicists are revisiting what they previously assumed about how dark matter interacts with itself.
Whether he is on the side of a mountain or working at the Fermilab Quantum Institute, Cristián Peña likes to explore the unknown and tackle new challenges. Although he spends most of his time working on quantum communication systems for FQI, Peña dedicates time to work on the CMS experiment. His work between the two experiments, while different in practice, are conceptually similar.
