Himanshu Sharma

Physicist • Developer • Philosopher

Research Focus & AffiliationsBridging quantum light-matter interaction and classical AI. Actively researching across three groups - Nanophotonics, IITK, Photonic Devices, IITK, and Kyoto University's LLM Center - investigating Cavity-QED, Single-Photon Sources, and Mechanistic Interpretability.

I’m a third-year Physics major at IIT Kanpur driven by the ambition of building a fault-tolerant, practically useful Quantum Computer. Fascinated by the fundamental laws of the universe and computer systems, my research sits at their intersection, currently focusing on Cavity Quantum Electrodynamics and the simulation of open quantum systems for information processing.

I have an insatiable desire to understand this world, it's workings and it's purpose; and wish to acquire as much knowledge about as many things possible. Beyond physics, my intellectual curiosity frequently spills over into the Statistics, Machine Learning, Large Lanaguage Models and thier interpretabiliy.

When I’m not running quantum circuits or debugging neural networks, you’ll likely find me actively debating social issues, or exploring the philosophies of Camus and Nietzsche while sipping on a cup of cappuccino.
