Research Highlights
Margaret Murnane is a new honorary member of Optica — the most distinguished membership bestowed by the international society dedicated to optics and photonics.
In an article published June 11, 2026 in the journal Nature Physics, a team of JILA researchers led by JILA Fellow Adam Kaufman, in collaboration with researchers at the University of Innsbruck in Austria, report experiments demonstrating the versatility of ytterbium atoms as qubits. A neutral ytterbium atom is an adaptable chameleon that can be used as multiple styles of qubit, each bringing distinct advantages. Their experiments demonstrate a quantum multitool that can tackle quantum computations, quantum simulations and precise measurements of time and also combine the capabilities associated with each application.
Physics alumnus Alexander Aeppli (PhDPhys’25) is the recipient of this year’s Deborah Jin Award for Outstanding Doctoral Thesis Research, a national honor awarded by the Division of Atomic, Molecular and Optical Physics (DAMOP) of the American Physical Society. Aeppli received the award at the annual DAMOP meeting held June 1-5, 2026, in Providence, Rhode Island.
New research led by Professors and JILA Fellows Ana Maria Rey and James Thompson published in Physical Review X proposes a new entangled state for atoms in a quantum sensor. The team’s methods can be created quickly, and more importantly, faster as the system gets larger, making them practical for scaling quantum sensors.
Researchers at JILA propose a new superradiant laser design for next-generation “active” atomic clocks that eliminates atom-heating and vibration sensitivity, two major obstacles that have limited precision and practicality. By carefully guiding atoms through a controlled loop of quantum states, the approach could enable compact, robust atomic—and potentially nuclear—clocks that maintain extreme accuracy even under physical disturbances.
JILA researchers, working with collaborators in Germany, demonstrated that new crystalline mirror coatings dramatically reduce atomic-level noise in optical cavities, enabling lasers with record‑breaking frequency stability. By outperforming traditional coatings by a factor of four, these mirrors open the door to more precise experiments and future advances in technologies such as atomic clocks and gravitational‑wave detection.
JILA researchers have taken a major step toward realizing next‑generation nuclear clocks by studying how thorium‑doped crystals behave over time. In new experiments published in Nature, the team tracked the stability, temperature response, and reproducibility of three calcium‑fluoride crystals containing different concentrations of thorium. Over nearly a year of measurements, all three crystals demonstrated remarkably stable nuclear transition frequencies—an essential requirement for building reliable nuclear clocks.
JILA Fellow and ÂĚñ»»ĆŢ Physics Professor Heather Lewandowski and members of her lab have shattered a 25-year-old theory about how benzene forms in the interstellar medium, revealing that the long-accepted chemical recipe doesn’t work under space-like conditions. Their groundbreaking laser-cooling experiments open a new chapter in understanding the origins of complex carbon molecules in the cosmos.
In a study published in Physical Review X Quantum, a team led by JILA and NIST Fellow and ÂĚñ»»ĆŢ physics professor Jun Ye has demonstrated—for the first time—narrow-line laser cooling of a molecule. By utilizing a previously unaddressed transition in the diatomic molecule yttrium monoxide (YO), the researchers have developed a new approach to manipulate internal states and molecular motion with unprecedented precision.
For the past several years, an experimental research group led byĚýJILA Fellow James Thompson and a theoretical research group led by JILA Fellow Ana Maria Rey have been working together to study quantum interactions using cavity quantum electrodynamics (cavity QED)—the science of how light contained in reflective cavities interacts with quantum particles, like individual atoms. Recently, they tackled many-body interactions with a new experiment, described in an article published in the journal Science. In the experiment, they successfully created interactions that require the participation of either three or four atoms to achieve the observed results.
