Google Quantum AI has named JILA Fellow Adam Kaufman to lead a new neutral atom quantum computing hardware team, marking a major expansion of its quantum research program. Kaufman will continue his research at JILA and CU Boulder, strengthening JILA’s leadership and impact in national and international quantum science.

Since it was first proposed in 2004 by David Weiss and Maxim Olshanii, it has been a goal to see whether atomic rearrangement and high-fidelity ground-state laser cooling could employed to prepare superfluids and low-entropy many-body states of itinerant matter. In this work, we demonstrate such a protocol, opening a new path to assembling ground-state many-body state of bosonic and fermionic quantum systems. 

In quantum metrology, it has been considered for some time whether quantum error correction can be used to enhance precision measurements. Here, the primary challenge is devising codes ad protocols that correct noise while not correcting the unknown signal being sensed. In this collaboration with the Pichler, we identify some promising conditions for leveraging quantum error correction for enhanced sensing, even when signal and noise couple identically to sensor qubits. 

Our paper on preparing entangled states in Yb171 has been accepted in Nature physics! Congratulations to the team! We show high-fidelity gates in the metastable qubit, high-fidelity three-outcome measurements, and coherent mapping of entangled states between the Rydberg, nuclear, and optical qubits. This work suggests several new directions, including in quantum error correction, hybrid digital-analog quantum simulations, and quantum metrology. 

The U.S. Department of Energy (DOE) has announced a $625 million investment to advance the next phase of the National Quantum Information Science Research Centers, a cornerstone of the National Quantum Initiative. This funding will support five centers dedicated to accelerating quantum technologies that promise transformative impacts on science, industry, and national security. JILA is proud to remain a key partner in QSA through the Q-SEnSE Center, which focuses on quantum sensing and precision measurement.

Our work on high optical access cryogenic system for Rydberg atoms has been published in PRX Quantum - see this viewpoint on our studies.

We used features of alkaline-earth atoms to enhance the timescale coherent many-body physics using Rydberg-dressing, which enables studies of quantum magnetism and the creation of metrologically-useful entanglement. See the paper here. 

JILA Fellow, National Institute of Standards and Technology (NIST) Physicist and University of Colorado Boulder physics professor Dr. Adam Kaufman has been awarded the prestigious Presidential Early Career Award for Scientists and Engineers (PECASE).  President Joe Biden announced that this accolade represents the highest honor conferred by the U.S. government to early-career scientists and engineers who exhibit extraordinary potential and leadership in their respective fields. Kaufman’s groundbreaking contributions to quantum science have cemented his place among nearly 400 recipients recognized for their innovative research and commitment to advancing scientific frontiers.

Adam Kaufman, a JILA Fellow, NIST Physicist, and CU Boulder Physics Professor, has been awarded part of a $1.25 million grant from the Gordon and Betty Moore Foundation as part of its third annual cohort of Experimental Physics Investigators.

Dr. Matthew Norcia, a member of JILA’s extensive alumni network, has been awarded the prestigious 2024 International Union of Pure and Applied Physics (IUPAP) Early Career Scientist Prize in Atomic, Molecular, and Optical Physics. The IUPAP Early Career Scientist Prize honors early career physicists for their exceptional contributions within specific subfields, offering recognition through a certificate, medal, and monetary award.

JILA Fellow, NIST Physicist, and University of Colorado Boulder Physics Professor Adam Kaufman has been honored with a prestigious 2024 Friedrich Wilhelm Bessel Research Award by the Alexander von Humboldt Foundation. 

Aaron Young, a recently graduated Ph.D. student in the lab of JILA Fellow, NIST Physicist, and University of Colorado Boulder Physics Professor Adam Kaufman, has been awarded the prestigious 2024 Deborah Jin Award for Outstanding Doctoral Thesis Research in Atomic, Molecular, or Optical Physics by the American Physical Society (APS) for his work done at JILA. The award was announced in Fort Worth, Texas, at the 2024 55th Annual Meeting of the APS Division of Atomic, Molecular, and Optical Physics (DAMOP).

We recently demonstrated a new architecture for programmable control of Hubbard systems of neutral atoms. Here we used this platform to prepare and control systems of up to 180 particles. We study how their dynamics realize the boson sampling problem, originally formulated for photonics. You can read more about here. Congratulations to the team!!

We have demonstrated a family of multi-qubit gates to create GHZ states on the optical clock transition in strontium. We use these to show atom-laser clock comparisons below the standard quantum limit. We also create cascade GHZ states for large dynamic range phase estimation. Congratulations to the team!!

Our paper demonstrating the omg-architecture and mid-circuit operations in Ytterbium-171 has been published in PRX. Congratulations to the team!

After ~six very productive years, Aaron defended and graduated (on Nov. 1, 2023)! Congratulations Dr. Young! We are sad to see you go but very excited for your next adventure in the Greiner group!

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 (CU Boulder) and JILA, a joint institute of CU Boulder and the National Institute of Standards and Technology (NIST). 

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." 

Our paper reporting squeezing below the standard quantum limit in a programmable atom array has been published in nature! Congratulations to the team! Exciting to co-publish with the Browaeys/Yao and Roos/Rey teams too!

JILA Fellow, NIST Physicist, and University of Colorado Physics professor Adam Kaufman has been awarded a grant as part of the 2023 Young Investigator Research Program, or YIP. YIP was launched by the Air Force Office of Scientific Research, or AFOSR, the basic research arm of the Air Force Research Laboratory. The AFOSR's mission is to support Air Force goals of control and maximum utilization of air, space, and cyberspace. To do this, AFSOR is awarding $25 million in grants to 58 scientists and engineers from 44 research institutions and businesses in 22 states in 2023.
