JILA Fellow Murray Holland and his research team proposed an algorithm that uses the Quantum Fisher Information Matrix (QFIM), a set of mathematical values that can determine the usefulness of entangled states in a complicated system.

Their results, published in Physical Review Letters as an Editor’s Suggestion, could offer significant benefits in developing the next generation of quantum sensors by acting as a type of “shortcut” to find the best measurements without needing a complicated model.

On October 20th, Colorado Senator Michael Bennet visited JILA, a joint institute between the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder. During his visit, Bennet engaged with several of the institute's scientists and students, discussing their groundbreaking research and its implications. JILA Fellows Konrad Lehnert, Cindy Regal, Jun Ye, and Ana Maria Rey all spoke about their research during Bennett’s walking tour of JILA. Bennet visited Ye’s laboratory, discussing with several of his students the importance of atomic clocks and their impacts on technology such as GPS.

Bennet's engagement with JILA reinforces the significance of Colorado as a hub for scientific innovation and quantum research, and it sheds light on the potential collaborations that could emerge between political leadership and the scientific community.

JILA and NIST Fellow Ana Maria Rey and JILA Fellow and NIST Physicist Adam Kaufman have both been recently featured in an article for IEEE Spectrum. In a pair of Nature papers, Rey and Kaufman both demonstrated the phenomena of spin-squeezing to reduce noise in their quantum systems. "All objects that follow the rules of quantum physics can exist in multiple energy states at once, an effect known as superposition," explains the IEEE Spectrum article. "Spin squeezing reduces all those possible superposition states to just a few possibilities in some respects, while expanding them in others."

Leading the way in quantum sensing advancements, JILA, a renowned institute at the forefront of quantum sensing research, has once again proven its prowess. In a new Physics Magazine article, JILA graduate student Jarrod Reilly was highlighted in his work developing a groundbreaking approach that promises to redefine the capabilities of quantum sensors.

Opening new possibilities for quantum sensors, atomic clocks and tests of fundamental physics, JILA researchers have developed new ways of “entangling” or interlinking the properties of large numbers of particles. In the process they have devised ways to measure large groups of atoms more accurately even in disruptive, noisy environments.

The new techniques are described in a pair of papers published in Nature. JILA is a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder.

Ana Maria Rey, a JILA and NIST Fellow, has been honored with the prestigious 2023 Vannevar Bush Faculty Fellowship from the Department of Defense (DOD). The Vannevar Bush Faculty Fellowship, named after the visionary American engineer and science administrator, aims to support exceptional researchers with outstanding scientific and technological leadership. It provides recipients substantial financial support over five years, allowing them to pursue innovative and high-impact research endeavors.

A new approach recently described in Physical Review Letters explores a new way to generate squeezing that is exponentially faster than previous experiments and generates a new flavor of entanglement: two-mode squeezing—a type of entanglement that is thought to be used for improving the best atomic clocks and for sensing how gravity changes the flow of time. This promising new approach was developed by a collaboration of JILA and NIST Fellows Ana Maria Rey and James K. Thompson, and their team members, along with Bhuvanesh Sundar, a former postdoctoral researcher at JILA now at Rigetti Computing, and former JILA research associate Dr. Robert Lewis-Swan, now an Assistant Professor at the University of Oklahoma.

Election to the National Academy of Sciences (NAS) is one of the highest honors that can be bestowed upon a scientist in the United States, and it is a mark of recognition for exceptional scientific achievement. This achievement has now been bestowed on JILA and NIST Fellow, along with the University of Colorado Boulder physics professor Ana Maria Rey, as she was inducted into the NAS in 2023.

Some of the most important research and discoveries in science have been made by women. To celebrate these inspiring individuals and to support the next generation of female scientists, the United Nations dedicated February 11 as "International Women and Girls in Science" day. To honor this tradition, JILA hosted a panel discussion/open-forum with both JILA Fellows and JILA staff as speakers.

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 University of Colorado Boulder, 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.
