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.

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.

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.

The strange behaviors of high-temperature superconductors—materials that conduct electricity without resistance above the boiling point of liquid nitrogen—and other systems with unusual magnetic properties have fascinated scientists for decades. While researchers have developed mathematical models for these systems, much of the underlying quantum dynamics and phases remain a mystery because of the immense computational difficulty of solving these models.

Researchers at JILA and the University of Colorado Boulder have developed an innovative platform that combines machine learning with atom interferometry to create a universal quantum sensor. This system uses programmable atom-optic "gates" to reconfigure a single device via software for various precision measurements, such as acceleration, rotation, and gravity gradients, without the need for hardware changes.

Researchers at JILA, led by Ana Maria Rey, developed a new protocol for teleporting quantum information in collective spin states of ions within a two-dimensional crystal. This involves entangling ion groups through phonon modes and using measurements to transfer quantum states. The protocol, successfully simulated with up to 300 ions, shows potential for quantum networks and distributed quantum sensing.

Understanding how molecules interact with ions is a cornerstone of chemistry, with applications from pollution detection and cleanup to drug delivery. In a series of new studies led by JILA Fellow and University of Colorado Boulder chemistry professor Mathias Weber, researchers explored how a specific ion receptor called octamethyl calix[4]pyrrole (omC4P) binds to different anions, such as fluoride or nitrate. These findings provide fundamental insights about molecular binding that could help advance fields such as environmental science and synthetic chemistry.

With the recent launch of NASA's Europa Clipper, science takes a bold step closer to answering one of its most profound questions: could the building blocks for life exist beyond Earth? Aboard the spacecraft is the Surface Dust Analyzer (SUDA), a cutting-edge instrument designed to analyze tiny particles ejected from Europa's icy surface. These particles could provide crucial insights into the moon's hidden ocean and its potential to support life.

At the heart of this revolutionary instrument lies a critical component developed by LASP (the Laboratory for Atmospheric and Space Physics) with assistance from JILA’s W.M. Keck Lab: an iridium-coated titanium target that makes the high-precision analysis of cosmic dust possible. While LASP designed and built the instrument, their collaboration with JILA highlights the abilities of the University of Colorado Boulder’s institutes to tackle complex scientific and engineering challenges, advancing our understanding of the solar system and pushing the boundaries of exploration.
