Journey so far

2020-Now

EQUIP Lab, IIT Delhi

I am working on various experimental and theoretical studies on quantum optics having application in Quantum Technologies.

2018-2020

EQUIP Lab, IIT Delhi

I worked on setting up Quantum Technology lab. I developed in house delay line Mach Zehnder Interferometer for Quantum Key Distribution applications along with various experiments in free space and fiber based technologies.

2017-2018

Department of Physics, IIT Delhi

I worked on the problem of increasing dept of field with Prof. Kedar B Khare.

2013-2014

CRL, SXC Ranchi

I worked on the synthesis and characterisation of lead free ceramic materials with Dr Sumit Kr Roy
