Abstract: Engineered quantum systems, encompassing artificial mesoscopic structures governed by the principles of quantum mechanics, represent a cornerstone of modern quantum science. Notable examples include superconducting circuits, ultracold trapped atoms and ions, as well as electro and optomechanical systems. These systems are not only fascinating from a fundamental physics perspective but also serve as essential building blocks for technological applications.

Please join us for a JAGS Industry Spotlight Seminar featuring Micron. A networking session with the speaker will take place at 12:30pm followed by a technical presentation about the ongoing projects. 

Many-body localization (MBL) is a many-body quantum phenomenon that fails to thermalize under strong disorder. While experimental work on optical lattice systems suggests the existence of a MBL phase in 2D, there have been challenges regarding its existence in two dimensions. The main challenge of MBL in higher dimensions is an avalanche instability: rare regions of weak disorder can act as a thermal bath, which eventually thermalizes the entire system.

While electron microscopy enables imaging of individual atoms, the sample thickness is typically limited to a few hundred nanometers. Although super-resolution optical microscopy permits high-resolution visualization of subcellular structures, it requires staining of the sample. In contrast, EUV and X-ray microscopy allow imaging of entire biological cells and other thick specimens with spatial resolutions down to ~10 nm.

Abstract: Ultrafast infrared spectroscopy in its extension to nano-imaging provides access to vibrational and low energy carrier dynamics in molecular, semiconductor, quantum, or polaritonic materials. In addition, to simultaneously probe both ground and excited state dynamics we have developed ultrafast heterodyne pump-probe nano-imaging with far-from-equilibrium excitation.

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.

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.

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.
