Quantum Information Science & Technology
JILA and NIST Fellows Jun Ye and David Nesbitt, along with their respective teams, have recently been highlighted in the latest issue of the SPIE Photonics West Show Daily, a publication from SPIE. This highlight focuses on the recent advancements in the frequency comb breathalyzer apparatus that the researchers have built and tested, which looks at diagnosing COVID-19 and other diseases.
JILA researchers have upgraded a breathalyzer based on Nobel Prize-winning frequency-comb technology and combined it with machine learning to detect SARS-CoV-2 infection in 170 volunteer subjects with excellent accuracy. Their achievement represents the first real-world test of the technology’s capability to diagnose disease in exhaled human breath.
Every year the National Institute of Standards and Technology (NIST) and the Department of Commerce (DOC) grant honor awards in the form of Gold, Silver, and Bronze Medals. According to the DOC website: “the Gold and Silver Medals are the highest and second highest honor granted by the Secretary for distinguished and exceptional performance.” Two of JILA’s Fellows, Jun Ye, and Judah Levine, have been awarded these medals.
JILA (a world-leading physics research institute set up by NIST and the ñ) is part of a multi-university research group that will build quantum-based tools for space-based Earth sensing. NASA expects to award a $15 million grant for five years to the group of universities. This cohort includes researchers from the University of Texas at Austin, JILA, the ñ (CU), the University of California Santa Barbara (USCB), the California Institute of Technology (Caltech), and the U.S. National Institute for Standards and Technology (NIST). “The award establishes the Quantum Pathways Institute, supported by a NASA STRI (Space Technology Research Institute), led by Prof. Srinivas Bettadpur of the University of Texas at Austin, Texas, with CU and UCSB as collaborating institutions,” explained Dana Anderson, a JILA Fellow and ñ professor who is involved in the project. The Quantum Pathways Institute is the first of its kind, as it strives to translate the capabilities of quantum physics into usable devices called “Quantum 2.0.” Besides these developments, the Institute will offer educational training for graduate students and postdocs in quantum theory and quantum experimentation.
The CUbit Quantum Initiative at the ñ has appointed physics professor Noah Finkelstein to serve as faculty director of education and workforce. Finkelstein will lead CUbit’s establishment of a coordinated educational approach that cultivates leaders of the next-generation quantum workforce.
Associate JILA Fellow and ñ Assistant Professor Dr. Shuo Sun has been awarded a 2023 Sloan Research Fellowship. Along with 124 other winners, Sun's work has been recognized as being of the highest quality.
JILA and NIST Fellow Ana Maria Rey collaborated with NIST (National Institute of Standards and Technology) Ion Storage Group leader John Bollinger, and researchers at the University of Innsbruck, Rutgers University and the ñ, to design a trapped-ion simulator for 2D p-wave superconductors. Their work paves a way for clean observations of the predicted non-equilibrium dynamics in future experiments using the trapped-ion simulator, or Penning trap.
Quantum gases of interacting molecules can exhibit unique dynamics. JILA and NIST Physicist Jun Ye has spent years of research to reveal, probe, and control these dynamics with potassium-rubidium molecules. In a new article published in Nature, Ye and his team of researchers describe having combined two threads of previous research—spin and motional dynamics—to reveal rich many-body and collisional physics that are controllable in the laboratory.
When it comes to creating ever more intriguing quantum systems, a constant need is finding new ways to observe them in a wide range of physical scenarios. JILA Fellow Cindy Regal and JILA and NIST Fellow Ana Maria Rey have teamed up with Oriol Romero-Isart, a professor at the University of Innsbruck and IQOQI (Institute for Quantum Optics and Quantum Information) to show that a trapped particle in the form of an atom readily reveals its full quantum state with quite simple ingredients, opening up opportunities for studies of the quantum state of ever larger particles.
There are many methods to determine what the limits are for certain processes. Many of these methods look to reach the upper and lower bounds to identify them for making accurate measurements and calculations. In the growing field of quantum sensing, these limits have yet to be found. That may change, thanks to research done by JILA Fellow Graeme Smith and his research team, with JILA and NIST Fellow James Thompson In a new study published in Physical Review Applied, the JILA and NIST researchers collaborated with scientists at the quantum company Quantinuum (previously Honeywell Quantum Solutions) to try and identify the upper limits of quantum sensing.
