Jun Ye's research group has developed a groundbreaking laser system with record-breaking stability, crucial for advancing quantum technologies. By combining a highly stable silicon cavity laser with a frequency comb and a secondary cavity tuned for strontium atoms, the researchers created a laser capable of manipulating quantum states with unprecedented precision. Their system significantly reduces frequency noise, a major hurdle in quantum experiments, and demonstrated its effectiveness by achieving a new fidelity record in quantum gate operations on 3000 neutral atom qubits. This innovation paves the way for more accurate atomic clocks and scalable quantum computing.

JILA is proud to announce that Chuankun Zhang, a former graduate student in ÃÛÌÒ´«Ã½Æƽâ°æÏÂÔØ Physics professor and JILA and NIST Fellow Jun Ye’s research group, has been named a recipient of the prestigious 2025 Boeing Quantum Creators Prize. This national honor recognizes early-career researchers whose work is propelling quantum science and engineering in bold new directions.

In a groundbreaking study researchers at JILA have demonstrated continuous lasing and strong atom-cavity coupling using laser-cooled strontium atoms. This innovative experiment opens new avenues for precision measurement and quantum technologies, promising advancements in quantum sensing and metrology.

JILA and NIST Fellow and University of Colorado Boulder physics professor Jun Ye has been awarded a prestigious 2025 AB Nexus seed grant for his pioneering work in quantum sensing technologies.

In a new theoretical study, physicists at JILA and the University of Colorado Boulder have proposed a way to make the most precise clocks in the world even more robust—by weaving in the strange, protective properties of topological physics. Their work, published in PRX Quantum, explores how a class of quantum states known as symmetry-protected topological (SPT) phases could be used to improve the performance of optical lattice clocks, a cornerstone of modern precision measurement.

Physicists descended on the island of Helgoland this June to celebrate 100 years of quantum mechanics. Our group enjoyed contributing to this the convergence of quantum applications and foundations.

The first Bose-Einstein Condensate (BEC) was first created by Eric Cornell, Carl Wieman, Mike Anderson, Jason Ensher, and Michael Matthews on June 5, 1995 in JILA at the University of Colorado Boulder. This new state of matter was first predicted 70 years earlier. Satyendra Nath Bose first described the quantum statistics of what we now call bosons, and Albert Einstein extended the theory to show that non-interacting bosons could condense into a single macroscopic quantum state at low temperature.

In a new study, physicists at JILA and the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a feat that many scientists didn’t think was possible.

In a recent study published in Science, by JILA and NIST Fellows and University of Colorado Boulder physics professors Jun Ye and Ana Maria Rey, interactions between atoms are explored in depth, focusing on superexchange processes that occur in a three-dimensional optical lattice.

Professor Cindy Regal, Baur-SPIE Chair at JILA, has been named a 2025 Brown Investigator by the Brown Institute for Basic Sciences at Caltech.
