The U.S. Department of Energy (DOE) has announced a $625 million investment to advance the next phase of the National Quantum Information Science Research Centers, a cornerstone of the National Quantum Initiative. This funding will support five centers dedicated to accelerating quantum technologies that promise transformative impacts on science, industry, and national security. JILA is proud to remain a key partner in QSA through the Q-SEnSE Center, which focuses on quantum sensing and 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.

Our work on high optical access cryogenic system for Rydberg atoms has been published in PRX Quantum - see this viewpoint on our studies.

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

On June 20, 2024, the U.S. National Science Foundation awarded JILA and the University of Colorado Boulder a $20 million grant to create the National Quantum Nanofab (NQN), a cutting-edge facility poised to revolutionize quantum technology. 

JILA Fellow and University of Colorado Boulder physics professor Cindy Regal remarked, "The NQN will be a unique facility for quantum discoveries and technology. I look forward to seeing the NQN as a national resource in quantum and interfacing with a wide range of JILA research.”

Mechanical resonators featuring large tensile stress have enabled a range of experiments in quantum optomechanics and precision sensing. Many sensing applications require functionalizing tensioned resonators by appending additional mass to them. However, this may dramatically change the resonator mode quality factor, and hence its sensitivity.

In our work published in Physical Review Applied, we study how mode quality factor depends on suspending a mass on a type of membrane resonator known as a trampoline.  Surprisingly, the quality factor becomes independent of the mass in the large-load regime, for any tensioned resonator, which explains previous related results and will enable new design perspectives.

In our work recently published in Physical Review Research we study Rabi oscillations in a vapor cell environment to understand their coherence in a regime where strong population dynamics are present. With these efforts we take an important step towards applying ideas in vector magnetic field measurements using Rabi oscillations to vapor cells.

Regal is the first recipient for JILA's new endowed chair in optics and photonics.

A new national quantum research center draws on JILA Fellows' and their expertise to make the United States an international leader in quantum technology.

JILA Fellow Cindy Regal has been selected as the 2020 recipient of Research Corporation for Science Advancement’s Cottrell Frontiers in Research Excellence and Discovery (FRED) Award. The $250,000 FRED Award recognizes and rewards innovative research that could transform an area of science.

Analysis and new designs of low mass SiN mechanical defects in 2D acoustic shields for force sensing -- now published in Physical Review Applied.

We are organizing an upcoming workshop on optomechanical architectures for new physics searches through force signatures on scalable arrays of mechanical resonators.  The workshop is sponsored by an APS Moore Foundation Fundamental Physics convening award and co-sponsored by the JILA NSF Physics Frontier Center and JQI.  

Chris Kiehl, a graduate student in the Regal Group, won a prize for his poster on quantum sensing and metrology at a conference in Germany this summer. 

Microwaves report on the direction of a magnetic field!  Our work on self-calibrated atomic vector magnetometry has been published in Phys. Rev. Lett.  We show that a microwave polarization ellipse can be mapped with atomic transitions, and can serve as a useful three-dimensional reference.  Our next step is to translate this idea to atomic vapor cells to make an atomic vector magnetometer that can calibrate itself at any time.

JILA Fellow Cindy Regal has been named a 2018 Alexander M. Cruickshank Lecturer by the Gordon Research Conferences (GRC). This prestigious title is given worldwide to scientists at the top of their fields in the physical, chemical, and biological sciences. 

Cindy Regal was elected a 2016 APS Fellow "For observation of quantum radiation pressure noise on a macroscopic object, and establishing quantum control over individual neutral atoms."  

Fellows Cindy Regal and Konrad Lehnert have won the 2016 Governor’s Award for High-Impact Research in Foundational Science and Technology, CO-LABS announced today. JILA Chair Dana Anderson submitted the nomination of their joint research on building, studying, and using devices that exploit the strange and powerful properties of quantum mechanics. The nomination was entitled, The JILA Quantum Machine Team: Extending Mastery of Quantum Mechanics from Microscopic Particles to Human-Made Machines.

Adam Kaufman has been awarded the 2016 DAMOP Thesis Prize for his outstanding thesis research on assembling neutral atoms in optical tweezers, work conducted in the Regal group at JILA. As part of this  work, Kaufman and his coworkers developed an experiment that allowed the team to use laser cooling to assemble arrays of ground-state neutral atoms in optical tweezers. 

Graduate student Adam Kaufman received one of the poster prizes awarded at this year's International Conference on Atomic Physics in Washington DC.  His poster was entitled:  "Atomic Hong-Ou-Mandel effect in tunnel-coupled optical tweezers".

We have developed a method for imaging single neutral atoms during continuous Raman sideband cooling.  See our recent work in PRA.
