• Quantum information processing with non-Gaussian states:

One of the central focus of my research is to understand the role of exotic nonclassical and non-Gaussian features of optical states, and how these characteristics contribute to various tasks in quantum information science and technology. 

• Quantum Communication with hybrid atom-light entanglement: 

Hybrid atom-light entanglements, representing a DV-CV cross systems, are recently found play an important role in various quantum communication tasks such as entanglement-sharing, teleportation, testing distant Bell nonlocality etc. The major goal of my research is to uncover their potential in network information processing.

• Optical nonclassicality: 

A key part of this endeavor is identifying and quantifying the intrinsic "quantumness" of these optical states, particularly when such features act as resources in applied optics. An important strand of my research is the development of an experimentally viable, resource-theoretic framework to characterize this quantumness—commonly referred to as nonclassicality—within CV optical systems. 

• Quantum non-Gaussian state engineering:

Non-Gaussian states are crucial in improving performance in any linear optics based quantum information processing, in particular quantum computation with optical states. My research focus also encompasses generation of various useful non-Gaussian states and their efficient characterization.
