BS-MS in Science with a Major in Physics and a Minor in Mathematics
Research profile
I am a PhD candidate working as a theoretical support for the CAT-2 project of Quantum Delta, NL. I was awarded a Master's degree in Physics (with a Minor in Mathematics) by the Indian Institute of Science Education and Research (IISER), Mohali on the 26th of May, 2022. Currently, I am interested in continuous variable quantum key distribution (CVQKD), and other cryptography protocols involving continuous variable quantum states. I am also interested in the theoretical formalism of quantum mechanics and quantum information theory, which was also the topic of my Master's thesis, The Kirkwood-Dirac Quasi-probability: Characterising “Quantumness”.
