Strontium is an incredible element at the center of quantum physics tools and studies—most famously optical atomic clocks. While strontium atoms have one very long-lived excited state (which lives more than 100 seconds), they also have nicely accessible excited states. Those excited states are easier to access, but they are short-lived. A new proposal from the Rey Theory Group suggests a way to reach a dark state where the atoms can live in this excited state forever, opening new opportunities for clock technologies.

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.

For the first time, JILA scientists are able to observe dynamical phase transitions in an out-of-equilibrium system. They also found that they could undo the dynamical changes, reversing the experiment to where it started, which has great implications for understanding how the quantum world behaves and acts as a model for superconductors.

JILA Fellow Ana Maria Rey has been named a finalist for the prestigious Blavatnik Award for Young Scientists.

The holy grail of modern quantum science is to make a stable quantum computer. Now an experiment is on its way to create a quantum computer that is stable and can last longer using the sophisticated clock at JILA.

JILA researchers have proposed a simple experiment to realize and study rapid scrambling, the process by which quantum information spreads throughout a complex system and becomes inaccessible to simple local measurements, thus becoming apparently lost. Understanding rapid scrambling, as well as how it connects to chaos and entanglement, is key not only for building quantum computers but also for explaining open question about our universe such as the behavior of black holes and quantum gravity.

JILA researchers have, for the first time, trapped a single alkaline-earth atom and cooled it to its ground state. To trap this atom, researchers used an optical tweezer, which is a laser focused to a pinpoint that can hold, move and manipulate atoms. The full motional and electronic control wielded by this tool enables microscopically precise studies of the limiting factors in many of today’s forefront physics experiments, especially quantum information science and metrology.

JILA Fellows Dr. Tom Perkins and Dr. Konrad Lehnert both received medals from the Department of Commerce last night at the Ronald Reagan Amphitheater in Washington, D.C. Dr. Perkins received the Gold Medal, which is the highest honorary award given by the United States Department of Commerce, or DOC. Perkins was recognized for creating the world’s best atomic force microscope tailored to biological measurements. This device can “grab” onto biological molecules, such as proteins, and measure the tiny forces involved in their folding and unfolding.

Quantum computers are set to revolutionize society. With their expansive power and speed, quantum computers could reduce today’s impossibly complex problems, like artificial intelligence and weather forecasts, to mere algorithms. But as revolutionary as the quantum computer will be, its promises will be stifled without the right connections. Peter Burns, a JILA graduate student in the Lehnert/Regal lab, likens this stifle to a world without Wi-Fi. 

The chaos within a black hole scrambles information. Gravity tugs on time in tiny, discrete steps. A phantom-like presence pervades our universe, yet evades detection. These intangible phenomena may seem like mere conjectures of science fiction, but in reality, experimental comprehension is not far, in neither time nor space. Astronomical advances in quantum simulators and quantum sensors will likely be made within the decade, and the leading experiments for black holes, gravitons, and dark matter will be not in space, but in basements – sitting on tables, in a black room lit only by lasers.
