An international collaboration of physicists from India, Austria, and the USA—including JILA and NIST Fellow Ana Maria Rey, along with NIST scientists Allison Carter and John Bollinger—proposed that tweaking the electric fields that trap ions can create stable, multilayered structures, opening up exciting new possibilities for future quantum technologies.

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

The Heising-Simons Foundation's Science program has announced a generous grant of $3 million over three years, aimed at bolstering theoretical and experimental research efforts to bridge the realms of Atomic, Molecular, and Optical (AMO) physics with quantum gravity theories. Among the recipients, a notable grant was awarded to a multi-investigator collaboration spearheaded by the University of Colorado Boulder (���Ҵ�ý�ƽ������) and JILA, a joint institute of ���Ҵ�ý�ƽ������ and the National Institute of Standards and Technology (NIST).

Ana Maria Rey and her team discovered a method for how to not only create dark states in a cavity, but more importantly, make these states spin squeezed. Their findings could open remarkable opportunities for generating entangled clocks, which could push the frontier of quantum metrology in a fascinating way.

As a thermodynamic phase of matter, superconductors typically exist in an equilibrium state. But recently, researchers at JILA became interested in kicking these materials into excited states and exploring the ensuing dynamics. As reported in a new Nature paper, the theory and experiment teams of JILA and NIST Fellows Ana Maria Rey and James K. Thompson, in collaboration with Prof. Robert Lewis-Swan at the University of Oklahoma, simulated superconductivity under such excited conditions using an atom-cavity system.

Anjun Chu, a JILA graduate student, has been awarded the esteemed Boeing Quantum Creators Prize for 2023. This prestigious award, established by Boeing in 2021, celebrates early-career researchers who have significantly contributed to the advancement of quantum information science and engineering.

Chu, a member of the theory group led by JILA and NIST Fellow Ana Maria Rey, has distinguished himself through his groundbreaking research in quantum many-body dynamics. His work, focusing on spin systems and their multilevel extensions, has been vital in exploring quantum simulation and metrology in cutting-edge areas like optical lattice clocks and cavity QED systems.

U.S. President Joe Biden has awarded 232 Senior Executive Service (SES), Senior-Level (SL), and Scientific and Professional (ST) members across 31 government agencies with the prestigious Presidential Rank Award. Of these individuals, JILA and NIST Fellow Ana Maria Rey has been recognized within the Department of Commerce for her work in precision measurement and quantum physics.

JILA and NIST Fellow Ana Maria Rey and JILA Fellow and NIST Physicist Adam Kaufman have both been recently featured in an article for IEEE Spectrum. In a pair of Nature papers, Rey and Kaufman both demonstrated the phenomena of spin-squeezing to reduce noise in their quantum systems. "All objects that follow the rules of quantum physics can exist in multiple energy states at once, an effect known as superposition," explains the IEEE Spectrum article. "Spin squeezing reduces all those possible superposition states to just a few possibilities in some respects, while expanding them in others."

Opening new possibilities for quantum sensors, atomic clocks and tests of fundamental physics, JILA researchers have developed new ways of “entangling” or interlinking the properties of large numbers of particles. In the process they have devised ways to measure large groups of atoms more accurately even in disruptive, noisy environments.

The new techniques are described in a pair of papers published in Nature. JILA is a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder.

The JILA Physics Frontiers Center (PFC), an NSF-funded science center within JILA (a world-leading physics research institute), has recently been awarded a $25 million grant after a re-competition process.

This science center brings together 20 researchers across JILA to collaborate to realize precise measurements and cutting-edge manipulations to harness increasingly complex quantum systems. Since its establishment in 2006, the JILA PFC’s dedication to advancing quantum research and educating the next generation of scientists has helped it to stand out as the heart of JILA’s excellence.
