- 报告题目：Secure quantum communication in a large scale
- 报告摘要：The quantum internet is a long-term scientific vision, but the key challenges to achieving global quantum internet are security, practicality and distance. I will address our recent efforts to solve these challenges. I will primarily talk the progress on the measurement-device-independent and device-independent QKD protocols, the high rate chip-based quantum communication, the large-scale satellite-ground integrated quantum network and so forth.

From 2021 to 2023, she was an independent ITAMP postdoctoral fellow at Harvard University. Since 2023, she is a professor for theoretical physics at the University of Regensburg, Germany.
- 报告题目：A brief tour through the Fermi-Hubbard phase diagram via snapshots
- 报告摘要：In quantum many-body physics, we aim to understand and predict the exciting phenomena emerging from the interactions of many quantum particles. In the regime where numerical simulations become challenging and analytical insights are rare, quantum simulation experiments can provide a possible route to explore these systems. The native measurements of quantum gas microscopes are single site resolved, projective measurements of the quantum many-body state. In this talk I will use the paradigmatic Fermi-Hubbard model, a conceptually simple model of interacting fermionic particles, as an example to highlight different approaches to gain insights into quantum many-body problems from such quantum snapshots. The Fermi-Hubbard model is believed to capture many ingredients necessary to describe the physics of the cuprate materials, which exhibit high-temperature superconductivity, and has therefore been studied extensively. Snapshots as obtained from quantum simulation experiments provide a new perspective on this model, and allow for the evaluation of completely new observables. I will discuss novel ways to analyze such snapshots, ranging from non-local transformations to perform Hamiltonian reconstruction, to pattern search algorithms and machine learning approaches.
