Speaker Bio

Dr. Hebin Li is currently an associate professor in the Department of
Physics at Florida International University (FIU). He received his BS in
physics from Wuhan University and his PhD in physics from Texas A&M
University in 2010. After three-years of postdoctoral study at JILA, a
joint institute of University of Colorado at Boulder and National
Institute of Standards and Technology, Dr. Li joined FIU as an assistant
professor in 2013 and was later promoted to an associate professor in
2019. During his tenure at FIU, Dr. Li has established a successful
research program with a equipped ultrafast spectroscopy and quantum optics
lab. His research interest focuses on experimental study of many-body
quantum systems and their potential applications in quantum information
science. Dr. Li is a Senior Member of Optica (formerly OSA). He has won
awards including William R. Jones Outstanding Mentor Award (2021), Army
Research Lab Summer Faculty (2020), FIU Top Scholar (2020), FIU CASE
Research Award (2017, 2020, 2023) and Engagement Award (2023), and FIU
Faculty Senate Excellence in Research Award (2023).

Hope to see everyone in the talk on Friday. Please also note as in other
talks, the remote connection information will be provided by MediaTeam

Abstract

Future scalable and reliable universal quantum computers can be
more superior than classical computers for solving certain problems. To
fully harness the power of quantum mechanics, the quantum computing
platform must be a many-body system with interacting or coupled quantum
entities (qubits). For example, entangling multiple qubits requires
coupling and coherence. The behavior of an assemble of interacting
particles cannot be understood by a simple extrapolation of the
microscopic lawas of single particles. Instead, entirely new properties
can appear at each level of complexity, as pointed out by P.W. Anderson in
1972. Experimentally understanding new principles and laws in many-body
systems is essential for both fundamental many-body physics and ultimately
providing practical solutions for future scalable and reliable quantum
computers. In this talk, I will present our work in exploring many-body
systems that consist of single quantum entities including single atoms and
solid-state-based atom-like entities. Recent advances in the preparation
of these exotic singe quantum entities and in coherent spectroscopy
provide unprecedented opportunities. We can deterministically prepare a
few- or many-body quantum system of single quantum entities using a
bottom-up approach and use ultrafast coherent spectroscopy to study
many-body properties in these systems. For example, our results revealed
long-range dipole-dipole interaction between atoms with separation up to
tens of micrometers. We have also observed multi-atom Dicke states with a
scalable and deterministic number of atoms from two to eight atoms,
providing the prerequisite for generating entangled states of up to eight
atoms. The study of these systems contributes to fundamental understanding
of many-body physics as well as potential applications in quantum
information science.
