Foundations of quantum information theory

We investigate quantum foundational Problems, such that,  non-ideal measurements, sub-Planck structure, non-locality, contextuality, and macrorealism. Additionally, we also develop novel measures for quantifying quantum correlations. 

Quantum Computation 

We study various aspects of quantum mechanics to actively use them for solving complex problems that are difficult for classical problems to solve. Our research extends to algorithm designing,  quantum machine learning, measurement-based quantum computation, variational quantum algorithms, quantum error correction, as well as quantum-inspired classical computation. 

Quantum Communication 

One of the main challenges in developing a secure quantum communication network is the presence of environmental noise. Our research is centered on mitigating this noise within quantum communication networks. Additionally, we focus on estimating and improving the information transmission rate in noisy quantum channels.

Quantum Sensing and Metrology

Through utilization of non-classical states of light (e.g., cat state, compass state) we design and implement specially tailored quantum states for multiparameter estimation in quantum sensing and metrological applications.
