I am a doctoral researcher in Quantum Information and Computation at IIT Madras, supervised by Dr. Prabha Mandayam and co-supervised by Dr. Siddharth Dhomkar. My research focuses on noise models, decoherence mechanisms, noise-adapted quantum error correction, and machine-learning-based dynamical decoupling on superconducting qubits.

“Quantum computation is a distinctively new way of harnessing nature. It will be the first technology that allows useful tasks to be performed in collaboration between parallel universes.”
“Nature isn’t classical, dammit, and if you want to make a simulation of nature, you’d better make it quantum mechanical, and by golly it’s a wonderful problem, because it doesn’t look so easy.”
“Best part was the description of concepts along with codes. People who have little/weak background of quantum information can also benefit from the workshop. For the rest of the queries, mentors were always available.”
