Brief Bio
I am a joint PhD student at CQuERE (TCG CREST) and IIT Tirupati, with a strong interest in quantum computing and its potential to advance our understanding of complex quantum many-body phenomena. My work focuses on developing and applying quantum-computational methods to address challenging problems in quantum many-body physics. Beyond my academic pursuits, I enjoy exploring Bengali literature, discovering new music, and unwinding with web series and films.

Field of work at TCG CREST and supervisors (if any)
My research combines classical and quantum computational methods to study quantum many-body phenomena. I employ tensor network approaches—particularly DMRG-based Matrix Product States (MPS) and Time-Evolving Block Decimation (TEBD)—to study ground-state properties and non-equilibrium dynamics in ultracold atoms in optical lattices. I also utilise quantum algorithms, including NISQ and early fault-tolerant approaches, to simulate complex quantum many-body physics. Currently, I am exploring quantum annealing to investigate atomic properties in neutral atoms and heavily charged ions.
