Digital quantum simulation and error correction frontier with atom arrays

When
-

Abstract: Quantum processors have the potential to significantly advance our understanding of quantum systems. In particular, the programmability of digital quantum devices can enable access to highly tunable quantum dynamics and observables. The central challenge, however, is suppressing errors, making quantum error correction essential for large-scale algorithms.

Molecular Tweezer Arrays in the Quantum Many-Body Regime

When
-

Abstract: Optical tweezer arrays of laser-cooled molecules are an emerging platform for quantum science, combining the rich internal structure of molecules with the versatile microscopic control and detection capabilities of optical tweezers. In recent years, our lab has helped push the frontier of quantum control in this platform, demonstrating high-fidelity single-molecule imaging and state preparation, coherent control at both the single and two molecule level, and deterministic entanglement between individually prepared molecules.

Probing molecular mutual neutralization reactions of atmospheric importance using the ion storage facility DESIREE

When
-

Abstract: The evolution of plasma environments is defined and governed by balances between ionizing processes, chemical rearrangements, and neutralisation reactions such as mutual neutralisation (MN). Measuring and explaining these processes in detail is fundamental to understanding and modelling non-local thermal equilibrium environments, such as atmospheric plasmas.

High-Repetition-Rate Fermionic Quantum Gas Microscope for Quantum Simulation

When
-

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.

A compact dual-species setup towards ultracold fermionic 6Li87Rb molecules

When
-

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.

Broad-Spectrum Photonics from Visible to Infrared: Multiscale, Multiphysics Challenges and Active Nanophotonic Devices

When
-

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.
