The Rey Group
Principal Investigator
Ana Maria Rey
My research interests are in the scientific interface between atomic, molecular and optical physics, condensed matter physics and quantum information science. Specifically, on ways of developing new techniques for controlling quantum systems and then using them in various applications ranging from quantum simulations/information to time and frequency standards. My group wants to engineer fully controllable quantum systems capable to mimic desired real materials as well as to develop advanced and novel measurement techniques capable of probing atomic quantum systems at the fundamental level.

Diego Barberena
I received my B.Sc. in physics at Pontificia Universidad Católica del Perú in 2013 and received a M.Sc. degree in quantum optics at the same place in 2016. I enrolled in the Ph.D. program at the University of Colorado Boulder in 2017 and joined Professor’s Rey group at the end of the same year.
My interests encompass quantum technologies and their implementations in AMO and condensed matter systems, as well as the more theoretical aspects of these subjects. I am generally excited both by the possibilities offered by systems of cold atoms to simulate various complex phenomena and by the theoretical understanding of these phenomena themselves. I am currently studying collective coherent interactions of many atoms with a cavity.
Raphael Kaubruegger
I earned my B.Sc and M.Sc in Austria at the University of Innsbruck. During my master's program, I visited the University of Gothenburg in Sweden, where I conducted research on neural network-inspired variational wavefunctions for quantum many-body problems under the guidance of Prof. Jan Budich.
Subsequently, I started a Ph.D. at the University of Innsbruck and the Institute for Quantum Optics and Quantum Information (IQOQI) Innsbruck, supervised by Prof. Peter Zoller. My Ph.D. research centered on the application of variational quantum algorithms in the field of quantum metrology. The aim was to optimize parameterized quantum circuits for the generation of entangled states, such as squeezed states, and to enable measurements in an entangled measurement basis.
At the beginning of 2024, I joined Prof. Ana Maria Rey's group at JILA with the aim of developing innovative protocols for the quantum platforms being developed at JILA.
Dr. Miskeen Khan
I obtained my M.Phil (Electronics) at Quaid-i-Azam university, Pakistan. I further obtained my PhD (Physics) degree under the supervisions of Prof. José Tito Mendonça and Dr. Hugo Tercas in 2021 at Instituto Superior Técnico, university of Lisbon, Portugal. I also worked as a visiting PhD student in the group of Prof. Maciej Lewenstein at ICFO-The Institute of Photonic Sciences, Spain.
During my PhD, I worked on theoretical modelling of various hybrid quantum devices that are mainly composed of the mechanical degrees of freedom. As such, I addressed the open system dynamics and the control of phonons while these are coupled to other quantum systems such as, light, atomic spin systems, and quasi-particle excitations.
Since October 2021, I joined Rey's group as a postdoctoral fellow. I am interested in the development of novel quantum devices that contribute in the developments of quantum technologies.

Graduate Student
Sanaa Agarwal
I graduated from Birla Institute of Technology and Science, Pilani (BITS Pilani) in Rajasthan, India with a double-major in Physics and Mechanical Engineering in 2019. I joined CU Boulder as a graduate student in 2019 and joined Prof. Rey's group in the summer of 2020. I am currently working towards understanding the effects of dipole-dipole interactions in multi-level atoms and drawing comparisons with the widely-studied case of two-level atoms in optical lattices. The understanding of light-matter interactions in these systems is pertinent to experiments involving alkaline-earth atoms with hyperfine levels and a degenerate ground-state manifold.

Anjun Chu
I obtained my B.Sc. in physics at Tsinghua University in 2018, and subsequently became a Ph.D. student in the Rey Theory Group at the University of Colorado Boulder. My research interests are mainly in the realization and characterization of exotic quantum many-body phenomena in highly controllable ultracold atomic systems. I'm currently focusing on the non-equilibrium dynamics in quantum spin model based on trapped bosonic gas platform and photon-mediated interactions of alkaline earth atoms in optical cavity.
Yongju Hai
I received my B.Sc. and M.Sc. in physics at the Southern University of Science and Technology in Shenzhen, China, and subsequently joined the group as a Ph.D. student in 2023 Fall.
My interest lies in the intersection of quantum information physics and its practical applications in AMO and solid-state systems. I am excited about the controllability and versatility offered by the cold atom system to uncover new insights into many-body phenomena and enable novel applications such as precision metrology. I am currently working on manipulating many-body dipole-dipole interactions in optical lattice clocks, aiming to understand and leverage their intricate effects.

Haoqing Zhang
I earned my B.Sc in Physics from the University of Science and Technology of China in 2020. Subsequently, I started my Ph.D in Physics at the University of Colorado Boulder in fall 2020, and joined Professor Rey's research group one year later. My research interests are centered around quantum simulation and meteorology utilizing highly tunable quantum many-body systems. Currently, I am focused on the Hamiltonian engineering of quantum spin models using matter wave interferometers with cavity QED systems.
