Sagnik Bhattacharya

I am a fourth-year Electrical Engineering undergrad at the Indian Institute of Technology, Kanpur, broadly interested in Information Theory and Quantum Computing. I am also interested in Boolean functions and the intersection of statistical physics, theoretical computer science and coding theory.

My CV.

My most recent research has been on classical coding theory bounds under the guidance of Prof Adrish Banerjee. We were able to extend some well-known bounds in the Hamming metric to the Lee metric. Our submission to ISIT 2019 is under review. We have also worked on generalizing the Fourier analytic proof of the MRRW bound.

I spent the summer of 2018 in Hong Kong, have also working with Prof Sidharth Jaggi of The Chinese University of Hong Kong on communication using common randomness in the presence of an adversary. Our submission to ISIT 2019 is under review.

I have also worked with with Prof Rajat Mittal on lower bounds on the quantum query complexity of 'interesting' functions.

I have a blog called Thoughts, Quantized. Some recent posts:
जब मैं था तब हरी नहीं: A song by Kabir
Shannon's Channel Coding Theorem: The (highly) non-trivial content of Shannon's Channel Coding theorem
Travelogue: Old Bangkok: Adventures in the old city of Bangkok

Other things that I have worked on, along with papers and reports that I have written, can be found here.

I happen to have several non-academic interests. Open The Trove to find out more about them.

Some of my talks can be found here.
