About Me

Hello! My name is Harshdeep, and I enjoy exploring different areas within quantum computation and information. I am currently pursuing my Ph.D. at the Centre for Computational and Data Sciences, Indian Institute of Technology (IIT) Kharagpur, where my research focuses on variational quantum algorithms and their applications in chemical systems.

Prior to this, I completed my Master’s Degree in Physics from Jadavpur University, where I conducted research on the theoretical study of the electrical and optical properties of Nickel-doped Molybdenum Disulfide (MoS₂). I also hold a Bachelor’s Degree in Physics from Jadavpur University.

I also have considerable experience in quantum machine learning and tensor networks. Throughout my academic journey, I have cultivated a strong foundation in both theoretical and computational aspects of physics, preparing me to contribute to cutting-edge research in quantum technologies.
