Quantum Information Science & Technology
In a new study, physicists at JILA and the °Ç¸ç³Ô¹Ï 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 °Ç¸ç³Ô¹Ï 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.
In a thrilling display of scientific communication and creativity, Thi Hoang, a graduate student at JILA, emerged victorious at the inaugural Quantum Science Slam held during the CLEO 2025 conference. This new event, designed to bring cutting-edge science to life for a broader audience, saw participants deliver engaging and entertaining 10-minute presentations on their research.
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 °Ç¸ç³Ô¹Ï 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.
Dr. Olivia Krohn, a former JILA graduate student and now a postdoctoral researcher at Sandia National Laboratories, has been awarded the prestigious Justin Jankunas dissertation award, given out by the American Physical Society (APS) division of chemical physics at the APS Global Summit conference. This award recognizes exceptional doctoral research that advances the frontiers of physics. Krohn’s award highlights her dissertation research, which bridges the legacy of JILA’s origins in astrophysics with its current role as a global leader in atomic, molecular, and optical (AMO) physics.
For decades, atomic clocks have been the pinnacle of precision timekeeping, enabling GPS navigation, cutting-edge physics research, and tests of fundamental theories. But researchers at JILA, led by JILA and NIST Fellow and °Ç¸ç³Ô¹Ï physics professor Jun Ye, in collaboration with the Technical University of Vienna, are pushing beyond atomic transitions to something potentially even more stable: a nuclear clock. This clock could revolutionize timekeeping by using a uniquely low-energy transition within the nucleus of a thorium-229 atom. This transition is less sensitive to environmental disturbances than modern atomic clocks and has been proposed for tests of fundamental physics beyond the Standard Model.
​A team of physicists at the °Ç¸ç³Ô¹Ï and the National Institute of Standards and Technology (NIST) has developed a groundbreaking laser-based device capable of analyzing gas samples to identify a vast array of molecules at extremely low concentrations, down to parts per trillion. Their findings were recently published in Nature.
