Nikhil Bansal

Hello.

I am a second year PhD student at the Department of Computer Science, University of Warwick where I am fortunate to be supervised by Matthias C. CaroLink opens in a new window. In my previous life, I was an undergraduate in Physics at IISER Mohali where I worked on Quantum Pseudo-randomness.

Research Interests.

My main research area is Quantum Computing and Information with focus on following sub-areas:

• Quantum Learning Theory
• Quantum Pseudo-randomness and Cryptography with Computational Assumptions
• Quantum Resources
