This is an ongoing project I am doing with Prof. Adrian Lupascu from the Institute of Quantum Computing, University of Waterloo which was made possible thanks to the MITACS Globalink scholarship. I developed numerical simulations for creating coupling between superconducting transmons using fixed capacitive coupling and a tunable coupling scheme involving mediated coupling with a transmon. We created a novel scheme for qutrit entangling gates using parametric coupling between transmons. This results in two kinds of entangling gates depending on the AC drive frequency and using three of these gates along with local rotations a CZ gate can be obtained.

This is a project that was part of my Bachelor's thesis that I did with Prof. Sai Vinjanampathy of The Indian Institute of Technology Bombay. In this project, we propose a variationally obtained optimal single-shot quantum channel discrimination task. This involves preparing a parameterized probe state and a parameterized two-outcome measurement both of which are optimized to minimize error probability. This algorithm was applied to the task of quantum illumination to obtain a probe state which matches the optimal performance of the two-mode squeezed vacuum state.

This is a project that did with Prof. Bhaskaran Muralidharan of The Indian Institute of Technology Bombay. We conceptualized a solid state spintronic setup for the detection of localized Zeeman splitting harnessing the inherent sensitivity of resonant tunneling. I performed simulations using the Keldysh (NEGF) method to benchmark the signal which the setup. I also analytically derived the quantum fisher information for the sensing task and compared with the classical fisher information from measurements using which I demonstrated the near optimality of resonant tunneling channels as sensing probes.
