Towards Macroscopic Quantum Superpositions
About us …
Our group shares a passion for understanding the physical world. The core question motivating our research is whether there is a limit to mass and complexity for observing unambiguous quantum phenomena. To address this question, we propose experiments that push the current boundaries of knowledge. We ensure the feasibility of our proposals by rigorously developing the underlying theories. This work requires an interdisciplinary approach to theoretical physics, as well as the ability to collaborate closely with experimental groups. We strive for excellence by combining scientific rigor with creativity.
