JILA has a long history in quantum research, advancing the state of the art in the field as its Fellows study various quantum effects. One of these Fellowsis Adam Kaufman. Kaufman and his laboratory team work on quantum systems that are based on neutral atoms, investigating their capacities for quantum information storage and manipulation. The researchers utilize optical tweezers—arrays of highly focused laser beams which hold and move atoms—to study these systems. Optical tweezers allow researchers exquisite, single-particle experimental control. In a new paper published in Physical Review X, Kaufman and his team demonstrate that a specific isotope, ytterbium-171 (171Yb), has the capacity to store quantum information in decoherence-resistant (i.e., stable) nuclear qubits, allows for the ability to quickly manipulate the qubits, and finally, permits the production of such qubits in large, uniformly filled arrays.

For JILA and NIST Fellows Ana Maria Rey and Jun Ye, one type of phenomena they are especially interested in observing are the interactions between light and atoms, especially those at the heart of the decay of an atom prepared in the excited state. Ye’s and Rey’s groups collaborated in a joint study, and were able to find an appropriate experimental setting where they were able to observe Pauli blocking of spontaneous emission by direct measurements of the excited state population.

Worldwide, many researchers are interested in controlling atomic and molecular interactions. This includes JILA and NIST fellows Jun Ye and Ana Maria Rey, both of whom have spent years researching interacting potassium-rubidium (KRb) molecules, which were originally created in a collaboration between Ye and the late Deborah Jin. In the newest collaboration between the experimental (Ye) and theory (Rey) groups, the researchers have developed a new way to control two-dimensional gaseous layers of molecules, publishing their exciting new results in the journal Science.

JILA Fellow Heather Lewandowski has been honored in the 2022  President’s Teaching Scholars Program (PTSP), which recognizes CU faculty who skillfully integrate teaching and research at an exceptional level. Lewandowski's laboratory focuses on both cold molecular physics and physics education research. Her physics education research program studies ways to increase students' proficiency in scientific practices such as using models and quantitative reasoning in experimental physics.

JILA and NIST Fellow Ana Maria Rey is to be inducted into the Colombian Academy of Exact, Physical and Natural Sciences (Academia Colombiana de Ciencias Exactas, Fisicas y Naturales). Fellow Ana Maria Rey has been inducted into the Colombian National Academy of Sciences.  Rey, is a Colombian-American physicist at the University of Colorado, Boulder who "studies the scientific interface between atomic, molecular and optical physics, condensed matter physics and quantum information science."

This week has been a big week for Colorado's quantum community, as delegates from the Government of Finland visited the snowy state to celebrate the beginning of several quantum research and quantum technology partnerships between the Fins and both academia and industry-based groups in Colorado.

JILA and NIST Fellow Jun Ye has been awarded the 2022 Herbert-Walther-Award from the German Physical Society and OPTICA (formerly OSA). This award recognizes distinguished contributions in quantum optics and atomic physics as well as leadership in the international scientific community.

JILA and NIST Fellow Jun Ye has been named a 2021 Clarivate Highly Cited Researcher. This means that Ye is one of the 0.1%, of the world's researchers who receive this title. Clarivate™ is a data analytics company that identifies the world’s most influential researchers ─ the select few who have been most frequently cited by their peers over the last decade. Ye’s many published papers over the last year have been ranked in the top 1% by citations for field and year in the Web of Science™, according to Clarivate. Well done Dr. Ye!

JILA and NIST Fellow Jun Ye has been awarded the Niels Bohr Institute Medal of Honor for 2021. This award was established in 2010 to mark the 125th anniversary of Niels Bohr’s birth. The medal is awarded annually to a particularly outstanding researcher who is working in international cooperation and exchange of knowledge, two qualities exemplified by Bohr himself.
