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.

Recently graduated Ph.D. researchers Bin Wang and Nathan Brooks, working with JILA Fellows Margaret Murnane and Henry Kapteyn, developed a novel method that uses short-wavelength light with a special vortex or donut shape to scan these repeating surfaces, resulting in more varied diffraction patterns. This allowed the researchers to capture high-fidelity image reconstructions using this new approach, which they recently published in Optica.

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."

William Carl Lineberger, 83, loving husband, died on October 17, 2023, in Boulder, Colorado. Born in 1939, in Hamlet, North Carolina, Carl was the only child of Evelyn Pilot Cooper and Caleb Henry Lineberger. He is survived by his wife, Kitty Edwards, and his beloved dog, Jude.

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.

JILA Fellow and University of Colorado Boulder professor Shuo Sun recently became the science advisor for Boulder-based quantum technology company Icarus Quantum. Since its inception in 2020, Icarus Quantum has focused on developing on-demand single- and entangled-photon generators for the future quantum internet network. As Sun's research focuses on quantum information science using photons (light particles) as a means to transmit information, he will no doubt be a valuable asset to this Colorado start-up.

The JILA Physics Frontiers Center (PFC), an NSF-funded science center within JILA (a world-leading physics research institute), has recently been awarded a $25 million grant after a re-competition process.

This science center brings together 20 researchers across JILA to collaborate to realize precise measurements and cutting-edge manipulations to harness increasingly complex quantum systems. Since its establishment in 2006, the JILA PFC’s dedication to advancing quantum research and educating the next generation of scientists has helped it to stand out as the heart of JILA’s excellence.

In a recent Science paper, researchers led by JILA and NIST Fellow Jun Ye, along with collaborators JILA and NIST Fellow David Nesbitt, scientists from the University of Nevada, Reno, and Harvard University, observed novel ergodicity-breaking in C60, a highly symmetric molecule composed of 60 carbon atoms arranged on the vertices of a “soccer ball” pattern (with 20 hexagon faces and 12 pentagon faces). Their results revealed ergodicity breaking in the rotations of C60. Remarkably, they found that this ergodicity breaking occurs without symmetry breaking and can even turn on and off as the molecule spins faster and faster. Understanding ergodicity breaking can help scientists design better-optimized materials for energy and heat transfer.
