Quantum Research Scientist

About

I am a PhD scholar in Physics with a deep interest in quantum information theory and its potential applications in computation and cryptography. My research explores how quantum systems process and transmit information, and how these principles can be used to develop new technologies. I have worked on understanding the optimal rate of classical information transmission through quantum channels under physical constraints, and explored how classical behaviour can emerge from quantum systems through a path-integral-based approach that includes weak measurements. I am also studying the limits of classical simulation of quantum computations, especially in systems that do not rely on entanglement or quantum discord. My long-term goal is to contribute to the development of quantum technologies by connecting foundational concepts with practical computational and cryptographic applications.
