“Quantum many-body dynamics of strongly interacting atom arrays”
The realization of large-scale controlled quantum systems is an exciting frontier in
modern physical science. In this talk, I will introduce a new platform based on cold atoms
in arrays of optical tweezers. We use atom-by-atom assembly to deterministically prepare
arrays of individually controlled cold atoms. A measurement and feedback procedure
eliminates the entropy associated with the probabilistic trap loading and results in
defect-free arrays of over 60 atoms. Strong controllable interactions between these atoms
are introduced by exciting them to Rydberg states. The resulting Ising-type interactions
lead to entanglement and non-trivial spatial correlations across the array. In particular,
we explore adiabatic transitions into crystalline states and study quantum dynamics of
this strongly correlated system in the vicinity of a phase transition. Prospects for
studying entanglement dynamics in many-body systems and the implementation of quantum
algorithms will be discussed.
Guest Presentation will begin at 4:30 PM
Refreshments will be provided.
