JILA and NIST Fellow and University of Colorado Boulder Physics professor Jun Ye and his team at JILA, a collaboration between NIST and the University of Colorado Boulder, have developed an atomic clock of unprecedented precision and accuracy. This new clock uses an optical lattice to trap thousands of atoms with visible light waves, allowing for exact measurements. It promises vast improvements in fields such as space navigation, particle searches, and tests of fundamental theories like general relativity.

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.”

One of the biggest challenges in quantum technology and quantum sensing is “noise”–seemingly random environmental disturbances that can disrupt the delicate quantum states of qubits, the fundamental units of quantum information. Looking deeper at this issue, JILA Associate Fellow and University of Colorado Boulder Physics assistant professor Shuo Sun recently collaborated with Andrés Montoya-Castillo, assistant professor of chemistry (also at CU Boulder), and his team to develop a new method for better understanding and controlling this noise, potentially paving the way for significant advancements in quantum computing, sensing, and control. Their new method, which uses a mathematical technique called a Fourier transform, was published recently in the journal npj Quantum Information. 

On Tuesday, May 28th, Governor Jared Polis made a historic visit to JILA, a joint institute established by the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder, to sign the recently passed Quantum Tax Credit Bill. This legislation aims to incentivize the adoption and development of quantum technology within Colorado, solidifying the state's position as a leader in this cutting-edge field.

While industry and academia tend to be the two main job trajectories after graduating with a Ph.D. or postdoctoral degree, some individuals, like Tanya Ramond, combine aspects of these careers in her role as Founder and CEO of Sapienne Consulting. 

“As an independent consultant, I am driven by a deep passion for commercialization and product strategy in deep tech areas,” Ramond elaborates. “These areas of technology are particularly challenging, often hardware-based, and heavily reliant on intellectual property. My expertise and enthusiasm extend to fields like quantum physics, optics, aerospace, and clean tech, inspiring those around me to push the boundaries of what is possible.” 

To highlight the pivotal role of federal funding in advancing quantum research, the National Science Foundation (NSF) hosted its inaugural Quantum Showcase on Capitol Hill two weeks ago.  The event highlighted the potential of government-funded quantum initiatives and included NSF-funded quantum researchers nationwide. JILA, a joint institute between the University of Colorado Boulder and NIST, was represented at the event by JILA Fellow and University of Colorado Boulder Physics Professor Heather Lewandowski and JILA graduate student Qizhong Liang, a member of JILA and NIST Fellow Jun Ye’s research group. 

In daily life, when two objects are “indistinguishable,” it’s due to an imperfect state of knowledge. As a street magician scrambles the cups and balls, you could, in principle, keep track of which ball is which as they are passed between the cups. However, at the smallest scales in nature, even the magician cannot tell one ball from another. True indistinguishability of this type can fundamentally alter how the balls behave. For example, in a classic experiment by Hong, Ou, and Mandel, two identical photons (balls) striking opposite sides of a half-reflective mirror are always found to exit from the same side of the mirror (in the same cup). This results from a special kind of interference, not any interaction between the photons. With more photons, and more mirrors, this interference becomes enormously complicated.

Measuring the pattern of photons that emerges from a given maze of mirrors is known as “boson sampling.” Boson sampling is believed to be infeasible to simulate on a classical computer for more than a few tens of photons. As a result, there has been a significant effort to perform such experiments with actual photons and demonstrate that a quantum device is performing a specific computational task that cannot be performed classically. This effort has culminated in recent claims of quantum advantage using photons.

Now, in a recently published Nature paper, JILA Fellow and NIST Physicist and University of Colorado Boulder Physics Professor Adam Kaufman and his team, along with collaborators at NIST (the National Institute of Standards and Technology), have demonstrated a novel method of boson sampling using ultracold atoms (specifically, bosonic atoms) in a two-dimensional optical lattice of intersecting laser beams. 

JILA and the University of Colorado Boulder's Department of Physics proudly announce two 2024 Physics Department Teaching Award recipients: JILA Fellow and NIST Fellow and Professor Eric Cornell and JILA Fellow and  Professor John Bohn. These awards recognize their exceptional dedication to teaching and their profound impact on students at different levels of their academic journey.

Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom “recoils” in the opposite direction, making it difficult to measure the position and momentum of the atom precisely. This recoil can have big implications for quantum sensing, which detects minute changes in parameters, for example, using changes in gravitational waves to determine the shape of the Earth or even detect dark matter. 

In a new paper published in the Science, JILA and NIST Fellows Ana Maria Rey and James Thompson, JILA Fellow Murray Holland, and their teams proposed a way to overcome this atomic recoil by demonstrating a new type of atomic interaction called momentum-exchange interaction, where atoms exchanged their momentums by exchanging corresponding photons. 

Using a cavity—an enclosed space composed of mirrors—the researchers observed that the atomic recoil was dampened by atoms exchanging energy states within the confined space. This process created a collective absorption of energy and dispersed the recoil among the entire population of particles.

Luke Coffman, a dedicated undergraduate research assistant at JILA, part of the University of Colorado Boulder, has been awarded the prestigious Goldwater Scholarship for the 2024 academic year. This award places Coffman among a select group of 438 students nationwide recognized for their significant achievements and potential in science, technology, engineering, and mathematics research.

While it may not look like it, the interstellar space between stars is far from empty. Atoms, ions, molecules, and more reside in this ethereal environment known as the Interstellar Medium (ISM). The ISM has fascinated scientists for decades, as at least 200 unique molecules form in its cold, low-pressure environment. It’s a subject that ties together the fields of chemistry, physics, and astronomy, as scientists from each field work to determine what types of chemical reactions happen there. 

Now, in the recently published cover article of the Journal of Physical Chemistry A, JILA Fellow and University of Colorado Boulder Physics Professor Heather Lewandowski and former JILA graduate student Olivia Krohn highlight their work to mimic ISM conditions by using Coulomb crystals, a cold pseudo-crystalline structure, to watch ions and neutral molecules interact with each other. 

At the 2024 Conference of World Affairs, held at the University of Colorado Boulder, two prominent figures in the Colorado quantum industry shared their insights into the rapidly evolving quantum technology landscape. Dana Anderson, a JILA Fellow, CU Boulder professor of Electrical Engineering, and the CSO of Infleqtion (previously ColdQuanta), joined forces with Corban Tillman-Dick, CEO and Founder of Maybell and chair of Elevate Quantum, a consortium of over 80 quantum-focused companies in Colorado.
