Abstract: The search for a unified theory that describes quantum matter and gravity is a long standing quest in theoretical physics. A fundamental hurdle still remains — we still lack empirical evidence to argue that gravity is fundamentally quantum in nature. The effects of quantum gravity are prominent at the scale of Planck length, which is beyond our current experimental capacity. However, with the use of quantum information theory, there have been recent proposals based on entangled particles which can shed light on the quantum nature of gravitational fields. In this talk, I will discuss the experiments proposed by Bose et. al.(2017) and Marletto and Vedral (2017) along with their theoretical motivations, possible outcomes and their implications, and challenges to the experiments. If time permits, I will also briefly discuss another experiment by Howl et. al. (2021) which is based on the evolution of Gaussian states.

About the Speaker: Ankit Wenju Shrestha completed his undergraduate studies at Ashoka University with a major in Physics and minor in Chemistry. He also completed his advanced major in Physics, working with Prof. Amin A. Nizami on a thesis titled 'Krylov Complexity for Floquet systems'. After working for an additional year as a research assistant with Prof. Nizami , Ankit went to the Department of Applied Mathematics and Theoretical Physics (DAMTP) at University of Cambridge to pursue Part III of  the Mathematical Tripos. His research interests include quantum chaos, foundations of quantum mechanics, and quantum information theory.

We look forward to your active participation.
