How does a scientist become interested in quantum physics? For Ana Maria Rey, both a JILA and NIST Fellow, the answer involves a rich and complicated journey. Quantum Systems Accelerator, a National QIS Research Center funded by the United States Department of Energy Office of Science, featured Rey in a new article series in honor of Hispanic Heritage Month. In this article, Rey shares her story and her current research.

Atomic clocks are essential in building a precise time standard for the world, which is a big focus for researchers at JILA. JILA and NIST Fellow Jun Ye, in particular, has studied atomic clocks for two decades, looking into ways to increase their sensitivity and accuracy. In a new paper published in Science Advances, Ye and his team collaborated with JILA and NIST Fellow Ana Maria Rey and her team to engineer a new design of clock, which demonstrated better theoretical understanding and experimental control of atomic interactions, leading to a breakthrough in the precision achievable in state-of-the-art optical atomic clocks.

Adam Kaufman — a JILA Fellow, NIST (National Institute of Standards and Technology) Physicist, and �Ǹ�Թ� Professor — has been awarded the American Physical Society's (APS) 2023 I.I. Rabi Prize in Atomic, Molecular, and Optical (AMO) physics.

�Ǹ�Թ�, Colo. — Physicist Adam Kaufman of both JILA and the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) has been awarded the 2023 New Horizons in Physics Prize from the Breakthrough Prize Foundation for his work in advancing the control of atoms and molecules to improve atomic clocks and quantum information processing.

In a new paper published in PRX Quantum, Rey and her team of researchers proposed a new method for seeing the quantum effects enabled by SU(n) symmetry in current experimental conditions, something that has been historically challenging for physicists.

Many researchers at JILA study and use superposition and entanglement of quantum systems, including JILA fellow Adam Kaufman. Previously, Kaufman and his research team focused on improving the coherence time of the strontium atoms’ superposition between the ground state and the “clock” state, so named because these two states form the basis for state-of-the-art atomic clocks. As reported in two new papers, researchers from this lab have extended these studies to much larger system sizes, with an atom in a superposition of hundreds of locations, and separately, demonstrating optical clock entanglement with seconds-scale coherence time.

JILA Fellow Cindy Regal and her team, along with researchers at the National Institute of Standards and Technology (NIST), have for the first time demonstrated that they can trap single atoms using a novel miniaturized version of “optical tweezers” — a system that grabs atoms using a laser beam as chopsticks.

The DoD announced today the selection of nine distinguished faculty scientists and engineers for the 2022 Class of Vannevar Bush Faculty Fellows (VBFF). This highly competitive Fellowship is named in honor of Dr. Vannevar Bush, who directed the Office of Scientific Research and Development after World War II. In line with Dr. Bush’s vision, the Fellowship aims to advance transformative, university-based fundamental research.

“The Vannevar Bush Faculty Fellowship is the Department’s most prestigious research grant award,” said Dr. Jean-Luc Cambier, the VBFF Program Director. “It is oriented towards bold and ambitious ‘blue sky’ research that will lead to extraordinary outcomes that may revolutionize entire disciplines, create entirely new fields, or disrupt accepted theories and perspectives.” JILA and NIST Fellow Jun Ye has been distinguished as one of the 2022 Fellows.

This year, JILA celebrates its 60th anniversary. Officially established on April 13, 1962, as a joint institution between the �Ǹ�Թ� and the National Institute of Standards and Technology (NIST), JILA has become a world leader in physics research. Its rich history includes three Nobel laureates, groundbreaking work in laser development, atomic clocks, underlying dedication to precision measurement, and even competitive sports leagues. The process of creating this science goliath was not always straightforward and took the dedication and hard work of many individuals.

More than 400 years later, scientists are in the midst of an equally-important revolution. They’re diving into a previously-hidden realm—far wilder than anything van Leeuwenhoek, known as the “father of microbiology,” could have imagined. Some researchers, like physicists Margaret Murnane and Henry Kapteyn, are exploring this world of even tinier things with microscopes that are many times more precise than the Dutch scientist’s. Others, like Jun Ye, are using lasers to cool clouds of atoms to just a millionth of a degree above absolute zero with the goal of collecting better measurements of natural phenomena.
