Fermionic quantum simulators provide a powerful platform for exploring high-temperature superconductivity, topological phases, and many-body dynamics—challenges that persist even with the advent of qubit-based quantum computing. In this talk, I will present recent results from our high-repetition-rate fermionic quantum gas microscope, which is optimized for rapid data acquisition. Fast cycle times on the order of a few seconds are achieved through high-power optical traps, rapid evaporative cooling, and efficient spin-resolved fluorescence imaging.

Long-lived optical clock states of alkaline earth and alkaline earth-like atoms have many applicati

Ultracold polar molecules possess inherent strong electric dipole moments and a rich internal structure, making them ideal platforms for implementing novel quantum information schemes, performing precision quantum metrology, and exploring exotic quantum phases such as dipolar BEC-BCS crossover in molecular Fermi gases. However, such experiments require extensive control over two or more species of atoms and their interactions, significantly scaling up the complexity and construction period of the experiment setup.

In this talk, Shinho Kim will discuss photonic systems studied across distinct spectral regimes, from the visible to the mid-infrared. His work addresses multiscale and multiphysics challenges in light–matter interactions, with each spectral regime involving fundamentally different mechanisms and applications.

Neutral-atom arrays with single-particle detection and control are a powerful tool for quantum science. In this defense, I present results from two projects, both performed with the same tweezer-programmable neutral-strontium-array apparatus. First, we engineer Rydberg interactions to create entangled spin-squeezed states, whose measurement noise can outperform classical limits. In a synchronous optical-frequency comparison between two spin-squeezed ensembles of atoms, we realize a measurement with a stability better than the standard quantum limit.
